Hi A,
Jalen is right that we'd like to steer customers towards TMP235. However, we understand that many products are hard to source today. LM94022 is a good alternative to LMT86. LM94021 could be an alternative, but please check the load regulation spec…

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°C temp…
Hi Bob,
I would like to know what is expected LM94022 output and ADS112U04 outpt with Temperature sensor mode disabled / enabled at temperature -55°C? Does ADS give lowest 16-bit value 8000h as an output or it's not guaranteed? Can ADS112U04 outputs…
Story gets even better when +24v supply switcher also powers DC inverter the low side recently replaced LM94022 reports correctly. When +80v linear powers DC inverter, also has isolated regulated +24v powering +5v buck down into +3v3 LDO (on PCB) both…

I have been pondering ramifications ADC SNR by 20K pull downs near the MCU pins tied to digital ground, 6 PWM outputs. The…
Hi Bob,
It seems odd that simply pinning two AINx inputs to +3v3 or GND return different FIFO results data depending on the sequencer step being sampled. Flipping the same two AINx steps GND to +3v3 and the FIFO integer results data may or may not be consistent…
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…
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…
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…

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 analog…
