Other Parts Discussed in Thread: TLV2381 I have been asked to answer this question for a co-worker of mine. We have a circuit that is basically a mic pre-amp/filter. It consist of a INA and a couple TLV2381's. All ICs are operating at +/- 3.3V. The normal…
Other Parts Discussed in Thread: TINA-TI , TLV2381 i need help designing an inverting op amp circuit that adds a bias to a signal as well as a gain. This seems to be very simple but for some reason i am having trouble bread boarding it up. Thanks
Hello Fanpeng,
You mention the TIA's power should be less than 100 uW. If the power supply used is a single 3 V source for example, then the maximum current would be I = P/E, I = 100 uW/ 3 V = 33 uA. There are a number of precision operational amplifiers…
The OPA145 also looks like a good choice, this file has not been recently updated so the OPA196 is not in yet, and the pricing is out of date.

to User473,
I searched all the op amp portfolio with the parametric search (precision, general purpose, and high-speed). There are 6 options with temperatures of 150C and above (see attached). The best match is the OPA211-HT (210C max). This is the…
