Part Number: OPA2140 Dear Expert,
We need to measure some electrical parameters of OPA2140; At present, testing has found significant differences between the parameters of quiescent current and input impedance and those in the data manual. 1. quiescent…

Hi experts,
Could you pick up some recomended opamps which have higher frequency and lower noise than OPA2140 as a replacement? My first thought is OPA2828. …
Part Number: OPA2140 Hi,
The differential single-ended conversion circuit using OPA2140AIDGKT is generating heat. I would like you to check the circuit diagram, so is it possible for me to discuss it with you via private message?
Thanks,
Conor
Part Number: OPA2140 I asked this question few months ago and the answer was the part will be released in April-May 2022: Is it already released or still in pre-release state?
Part Number: OPA2140 Has the OPA2140AIDRGR been released? based on previously provided info, it was supposed to be released in Nov-2021. there is no info on this part, except a couple of forum messages. can you provide the part's status and availability…
Part Number: OPA2140
I need OPA2140 dual amp in DRG package. I found POPA2140AIDRGR, however it is not RoHS part. The data sheet advises contact TI on this part. What is part's production status? Is it RoHS part?
Part Number: OPA2140 Hello,
We have a design where the minimum consumption on both amplifier power supplies (+/-12V) is a key design driver.
- What is the minimum quiescent current per amplifier to be considered ? At room temperature and in the whole…
Part Number: OPA2140 Hello，
Our customer used OPA2140 as 0~24mA current source, there is no problem during simulation, but actually, he met a question using PCB to test.
1) single 12V power supply, 0~2V input, and output 0~24mA, there is no problem…
Part Number: OPA2140 My customer wants to use OPA2140AIDGKR with baking condition 24hour 125C.
Is it acceptable baking condition ?
Best Regards
