This must be the oddest USB interruption tracked down to ADC1 sequencer 1 samples of two LM94022 temperature sensors. They both were very stable at idle reporting into the USB device client. When PWM0 was crunching the DC inverter one sensor was rolling…
Besides the ANIx inputs PE1,2 PK0 have voltage cycling on pins when idle and active SS1 or SS2 AINx source pins float near 158mV if not pulled down via 10K, was not expecting input pins to float so high.
That discovery lead to PK0 was not behaving…
Part Number: LM94021 Other Parts Discussed in Thread: TMP235 , TMP235-Q1 , , LM94022 , LMT86
Team,
Looking at available alternative to LMT86QDCKRQ1. The LM94021 is on stock on TI.COM. Can it be an option and what needs to be taken into account?

Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: LM94022
Did not add in post AIN-16 is the last (configured) analog input but there are three more (AIN-17,18,19) on the end (PK1,2,3) respectively that will later be populated LM94022 and an…
Part Number: TPS735 Other Parts Discussed in Thread: LM94022 , INA240 , , TPS737
Hello forum,
I have system with 2x 73533 LDO regulator input +5v04. One LDO has +3v307 isolated output to feed several discrete TI devices. The other supply MCU (105…
Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: LM94022
The gremlins seem to get more active when potentials around the ADC channels are elevated above 24v. The very last channel scanned (AIN-16) for conversion appears to spit out perhaps…
Part Number: UCD9246 Other Parts Discussed in Thread: LM57 , LM94022 , UCD74120 We would like to use the LM57-10 to measure the board temperature of our UCD9246 based design. This will be fed directly into the "TEMPERATURE" pin, w/o a mux.
Fusion Digital…
Part Number: TM4C1294KCPDT Other Parts Discussed in Thread: LM94022 ADC1 Sequencer 1 AIN16 (step 0) FIFO rolls mixed hex values compared to very quite AIN9 (step 1), both have sensor LM94022. Reversing sequencer steps moves the noise to AIN9 step 0 ,…
Hello,
Thank you for your inquiry. We do not have specific maximums for the rows you pointed out, thus it would be +/-2.7C. If you are looking for better accuracy please check out the LM94022. The LM94022 is a drop in replacement for the LMT86.
Thank…
It Would seem ADCSSEMUX being set to 0x1 in order to select MUX channels (19:16) is being ignored. Thus SSMUX2 AND's 0xF00 >> 8 any bits of MUX0-3 to form the AINx channel decodes. So PIN_IPHASEA (0x101) after AND right shift 8 = 0x001, any sequencer…
