Is it over 1.5V? Measure top of pin2, is it 0V? If pin 5 voltage is lower, try removing R2, so that pin 5 is open. Does output change properly? Is R2 really 620k?https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667857/tlv7011-tlv7011-input-voltage-range-and-absence-of-input-to-vcc-clamp-diode/6429820Mon, 27 Jul 2026 14:12:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:86b23994-e20f-42d1-b67e-74008b4c6409Marek LisThe inputs of TLV7011 and TLV7012 are fault tolerant - see below. Thus, you are correct to assume that there are no ESD diodes between the inputs and Vcc. The Recommended Operating Table is incorrect. Instead, for correct Vcm range please take a look at the Electrical Characteristics specifications table - see below.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667859/tlv3603-tlv3603-comparator-output-floats-high/6429772Mon, 27 Jul 2026 13:34:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4e8d608d-2728-415a-ae96-ea46a0750566Naddy MYApologies, I forgot to mention something that's important for the context of my troubleshooting point no.3: the reference voltage is controlled by potentiometer Plus these circuits were built on a PCB.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667859/tlv3603-tlv3603-comparator-output-floats-highMon, 27 Jul 2026 13:29:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5c7bb399-1516-4aa1-a67b-3b14b5ab4535Naddy MYPart Number: TLV3603 Other Parts Discussed in Thread: LMH6559 , OPA846 Hi, I have a pulse (38Mhz, 12ps) going through a TIA (OPA846) and then to a buffer (LMH6559), before going to some RC filters circuit to average out/amplify the voltage of the pulse. The average voltage then will go through a comparator (TLV3603) and expected is to give a high 5V provided that the average voltage of the pulse (IN+ of comparator) is higher than the reference voltage (IN-). It works fine and as expected after the RC filters circuit. However, as it reaches the comparator, i could see the output is always high at the rail value (5V) despite removing my input pulse at the TIA. The Vavg after the RC circuits goes to 0 if i remove my input, but the same is not observed after the comparator where it stays at 5V, and im not entirely sure why. For reference, my Vavg is 3V and my Vref is 1V. The output is high 5V. But when I increase my Vref to 4V, I expected it to go low (0V) as Vref>Vavg, but it stays high. The same thing was observed when I removed my incoming pulse connected to the TIA, where the output from comparator remains high at 5V. Troubleshooting that I did: Probe and made sure the supply pin is 5V and GND Check voltage at pin 5 - it was 1.06V so its in hysteresis mode and not latch mode Made sure the potentiometer wiper is working and connected to the IN- of comparator (saw it from scope the ref voltage moves up and down) Please could I ask for some advice on this comparator issue.

Based on this specification, it appears that the device can tolerate an input voltage higher than the supply voltage. Can we therefore assume that TLV7011 does not include a clamp diode between the input pin and VCC? Also, I found a description stating that the input voltage range is "VCC – 0.1 V to VEE + 0.2 V." Since the upper limit is shown as VEE + 0.2 V and the lower limit as VCC – 0.1 V, this seems reversed. Could you please confirm whether this is a typographical error and whether the correct range should be "VEE – 0.1 V to VCC + 0.2 V"?

Does this signal come from an external source, can it be touched, or is hot-plugging possible? Are there any protection components on this line?https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667554/tas5825m-what-s-the-max-output-power-mono-pbtl-8-ohm-24v-thd-n-1-10/6429548Mon, 27 Jul 2026 09:09:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c0e9ead3-0674-4daf-90cf-cc0f8cc7ee92Wenbin Li1Hi Jian the 8 ohm load in PBTL will have a little higher output power than btl mode as the drop in RDS will be a little smaller. but you can use the value of 30W(1%) 38w (10%) for draft evaluation.

This is out of some 3,000 products, so not a common issue, but as we have no explanation for the failure, it is a concern. The OPA4192 on two of our products passed commissioniong tests and failed during testing after delivery to customers. The first unit showed a short between pins 11 and 12. The second showed a resistance of only 192 ohms between the same pins. The units were made approximately 1 year apart, almost certainly from different batches. Customer negligence is hard to rule out, but seems unlikely. We use three of the op-amp circuits for identical purposes, so the fact that the failure is seen in V+IN D in both failures is interesting. Perhaps the proximity of the pins is relevant here. Has anyone observed this failure before? Please let me know if more information is needed.OPA4192Aerospace & Defensehttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667619/lm7322-lm7322-100-ict-failure-electrical-discrepancy-on-post-pcn-material-dc-2616-vs-pre-pcn-dc-2527-2619Mon, 27 Jul 2026 04:02:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:5fc2340f-8a7c-4925-b4f7-33f4d8d50f04Siti Natasya YusoffPart Number: LM7322 Hi TI E2E / Applications Support Team, We are observing a 100% line failure rate at In-Circuit Test (ICT) on our manufacturing line specifically associated with a recent lot of LM7322MM/NOPB ( Date Code 2616 , marked CCO/CSO: DEU ). Previous date codes ( DC 2527 and DC 2619 ) pass 100% and operate as expected on the exact same board setup. While TI Quality confirmed that 3 returned unused units pass standard ATE screening at the test site, our internal component-level, bench, and board-level diagnostics reveal clear physical and electrical discrepancies introduced post-PCN: Key Technical Findings & Discrepancies 1. Component-Level Diode Check / Continuity Post-PCN Material (DC 2616): Unused ICs consistently register as an OPEN circuit across pin pairs: Pins 1 & 2 , Pins 1 & 3 , Pins 5 & 7 , and Pins 6 & 7 . Pre-PCN Baseline (DC 2527 / DC 2619): Measures a consistent diode voltage drop of 0.873V ~ 0.877V across those exact same pin combinations. 2. Board-Level & Bench Output Voltage Drop On our application circuit, Pin 1 (Out A) and Pin 7 (Out B) measure abnormally low at 4V – 6V . On pre-PCN material in the exact same circuit, output pins correctly read 11V . 3. Physical & Curve Tracer Verification X-Ray Analysis: Displays distinct internal die layout and internal bond wire / frame structural differences between DC 2616 (suspect post-PCN) and DC 2619 (known good pre-PCN). Curve Tracer: Confirms a distinct characteristic impedance shift between the two date codes. Questions for LM7322 Applications Engineering Die & Internal Architecture Changes: What specific internal silicon die revision, ESD structure, or manufacturing process changes were implemented in this PCN for LM7322? Diode Path / Impedance Shift: Why does the post-PCN internal layout read as an open circuit across input/output ESD diode check paths where pre-PCN material presents standard ~0.87V diode drops? Application Circuit Sensitivity: Are there specific circuit design constraints that differ on the new die revision, causing the output to clamp at 4V–6V instead of 11V? Note: We can supply schematic snippets, X-ray comparisons, curve tracer graphs, and board layout details upon request. Thank you for your technical support in helping us identify why this post-PCN die change passes ATE screening yet causes a 100% failure rate in our application circuit.LM7322https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667554/tas5825m-what-s-the-max-output-power-mono-pbtl-8-ohm-24v-thd-n-1-10/6429187Mon, 27 Jul 2026 01:56:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4d745437-c64d-4713-a830-10ad43244f95Shenghao DingOur expert will feedback you next working day.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1667587/dual-diyamp-evm-dual-diyamp-evm---four-years-later-documentation-and-landing-page-still-missing-ic-package-size-infoMon, 27 Jul 2026 01:24:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:73b432bc-3101-41eb-967c-e7b3d3437827Jon WesenbergPart Number: DUAL-DIYAMP-EVM Why, four years after another user reported this issue, have the product documentation and product landing page for this EVM board not been updated?

Output is digitized after a differential stage by a 16-bit-class ADC. Observed problem: RMS voltage on all three phases (Va, Vb, Vc) shows a slow, clean, repeating oscillation with a period of ~25.77s (0.0388Hz), amplitude 0.28-0.72% pk-pk. This is confirmed to be a real analog phenomenon, not a digital/firmware artifact — verified by direct multimeter measurement at the AMC3330 analog input, independent of the digitizing chain. Source side is stable Omicron CMC356. Measuring the actual current flowing in the divider loop directly (ammeter Fluke 87V in series) shows it fluctuating between approximately 24.6µA and 25.7µA, consistent with V/R for the divider, and this fluctuation is present and closely matched across all three independent phase channels simultaneously. Cross-check: an earlier board revision using INA333 for the same voltage sensing function (same resistor divider values, same test setup/source, same current-sensing chain) does NOT show this oscillation. It appears specific to the AMC3330-based design. Any input filter (differential cap / RC) configuration known to attenuate this specific low-frequency (~0.04Hz) common-mode disturbance, as opposed to the high-frequency chopping noise the standard input filter targets? Any guidance would be appreciated.
