Other Parts Discussed in Thread: ADS131M08 , LMP2022 , SN74LV4T125 , SN74AUP2G80 , SN74LVC2T45 , TCA9406 Hello, We are working on a medical robot and as a part of the system, we have designed an electronic board that we needed to calculate reliability…
Hello Javier,
Please see the OPA2325, OPA2335 and LMP2022 datasheets:

Hello,
One additional thing, I recommend increasing the resistors in the feedback of the LMP2022 by 10x. Having low values resistors in the feedback will increase the current consumption of the design. It may also limit the output swing of the amplifier…
It looks like the VOS in the OPA335 model is higher than shown in the datasheet.
The VOS of the LMP2022 model is very close to the data sheet's typical value.
That explains the difference you are seeing.
If you need an updated OPA335 model, please…
Part Number: OPA335 Other Parts Discussed in Thread: TINA-TI , , LMP2022 , OPA333 Tool/software: TINA-TI or Spice Models There must be something wrong with the OPA335 simulation model.
I built a differential amplifier with OPA335 at single supply. The…
Other Parts Discussed in Thread: LMP2012 , LMP2022 , LMP2012QML-SP Hello,
I've got a question about the input bias currents on the LMP2012 :
The "5V DC Electrical Characteristics" table in the datasheet specifies a typical input current of -3pA at…
Other Parts Discussed in Thread: LMP2012 , LMP2022 We use LMP2016 in a product, but the article is obsolete. We need:
- low offset/drift.
- 3.3V supply.
- Pretty good rail ot rail.
- Pricetag, less than 2USD@1k
Is there any substitute to LMP2016…
Hi David,
Yes, the OPA2333 and OPA2188 are chopper-stabilized. I'm sorry, I did not look carefully enough at the offset. I am actually really surpirsed how well the TLC2652 specifications holds up against state-of-the-art chopper-stabilied op amps.…
Mark,
Please refer to pg. 32 for Bob Pease's comment on LM335. He basically said that 0.1uF+22ohm is fine. The article also pointed out a way to validate the stability empirically if you're interested in other cap values.
