However, instead of providing the expected 2.5 V output, it is generating 3.3 V. We have checked the output rail for shorts, and no shorts were found. To set the output voltage to 2.5 V, we populated the resistor divider configuration with R181 (100 k) and R177 (31.6 k). However, the output voltage still remains at 3.3 V instead of the expected 2.5 V. The measured voltages at the IC pins are listed below, and the relevant schematic is also attached for your reference. R2_EN → 11.65 V R2_MODE → 0.01 V R2_SS → 1.8 V R2_PG → 3.2 V VCC_R2_IN → 11.7 V R2_VSET → 0.788 V VCC_2V5 → 3.2 V Could you please help us identify the possible cause of this issue? Thank you.

I reviewed the circuit. Purpose of the circuit Converts a -10V voltage input to 0V. Converts a +10V voltage input to 3.3V. Connect the circuit output to the A/D circuit of a microcontroller operating at 3.3 V. In practice, the OPA2991/OPA4991 is used. ①Is it okay to use the OPA2991/OPA4991? ②Is it acceptable to connect the negative power supply pin to GND? Thank you.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1661258/tlv9001-shdn-pin/6407043Tue, 07 Jul 2026 07:19:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:0dc56a1e-7a16-49b0-90b4-4929d44d5f0cClemens LadischThe inputs have clamping diodes to V+ and V−. If the supplies were disconnected, it would be possible for currents to flow from the inputs to the supplies. The shutdown function allows the opamp to be disabled while input voltages are present.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1661796/lmp8640-what-is-the-difference-between-the-lmp8640mke-h-nopb-and-the-lmp8640mkx-h-nopbTue, 07 Jul 2026 07:13:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:dd2fb9a4-f807-4822-a851-488d5b3f5426CHANYONG UMPart Number: LMP8640 Hello, What is the difference between the LMP8640MKE-H/NOPB and the LMP8640MKX-H/NOPB ?

Is the maximum operating temperature of 85 degrees for the LMH2110 an absolute temperature that the user must adhere to? There is quite a difference between the maximum operating temperature (85 degrees) and the absolute junction temperature (150 degrees). Is it absolutely not recommended to use the LMH2110 up to 105 degrees?

Regarding the Class-D Amplifier External Load Diagnostics application note shared by you, could you please confirm how reliable and robust this circuit is when implemented with the TAS5760M-Q1 for automotive applications? Has this circuit been validated by TI for production use?

There is an Sallen-Key-Filter at the output: 2. We measured the offset with an ADC behind the filter. Measurements with the multimeter at the OUT pin confirm the meausurements. 3. The offset was measured over the whole measurement range including 0A. 4. The Offset is up to 6mV at the output of the INA. 5. The measurements are done with a 1 Ohm Shunt Resistor. In previous samples the NC Pins was floating and we have not seen this offset.

The AC coupling capacitor C178 is blocking the DC information for the sag correction to work correctly. Would the customer be able to modify the following: Remove C178 and replace with a 0Ohm resistor Add back in R362 of 22uF and C356 at 47uF Remove C183 and replace with a 0Ohm resistor.

If there are any issues, we will contact you. Thank you.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1661038/tpa3118d2-question-about-tpa3118d2-package-dap/6406570Tue, 07 Jul 2026 00:53:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:4d6ff6bd-0d23-4927-94d3-c4ccaef713e1HiraHi Isaac, Thank you for the information. One clarification regarding the thermal (exposed) pad size of the IC that ships as TPA3118D2DAP: Looking at the datasheet (SLOS708G), I see two different dimensions and want to confirm which one corresponds to the actual exposed thermal pad on the IC: 3.71 × 3.81 mm — listed under "Thermal Pad Mechanical Data, DAP (R-PDSO-G32)" as the exposed pad dimension, or 3.25 × 3.45 mm — associated with the DAP0032C package/land drawing Could you confirm which value represents the true exposed thermal pad size of the IC I would receive when ordering TPA3118D2DAP? Best regards, Hirahttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1660880/lm2902-test-exception/6406481Mon, 06 Jul 2026 22:43:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:b6b827b5-cc8e-48c5-acf2-173ffb80bad9Alex CurtisHi RuiPing, The high level output voltage of the LM2902 is specified with a minimum of VCC-1.5V at 25C with a 10Kohm load. Under the other datasheet conditions (VCC = MAX = 26V for the LM2902), with load greater than 10kOhms operating across the full temperature range, the typical high level output voltage is 24V (VCC-2V). With a 7V supply voltage, a high level output voltage of 6V instead of 6.4V is within the specifications of this device. Given that this issue occurs at low temperatures (Based on the test name " addrpriocold_3A_-40V_cold"), y ou may be able to improve the VOH level by changing the value of the pullup resistance, as described in section 5.2 of Application Design Guidelines for LM324 and LM358 Devices (Rev. B) . Let me know if you have any questions. Best, Alex Curtishttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1660951/ina241a-high-offset-after-connection-nc-pin-from-ina241a/6406416Mon, 06 Jul 2026 22:07:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:37834c26-427f-40d3-a1a1-c1dbb49b6275Joe VanacoreHello Markus, Thank you for your post. Can you provide the following: Schematic of the INA241 circuit with what is loading the output. How did you measure the offset voltage of the device? Is the offset you are referring to the 0A input condition? How large is the offset that you measured? What is the shunt resistor voltage during this high offset measurement? I want to first rule out a cause other than connecting the NC pin to +14V.
