Hey Tom, There is very little actual long term drift data out there on these kind of parts (seems the references do more of that). However, there is some data to suggest the chopper devices do really well - essentially your output long term drift is more…
Part Number: ADS1258 Other Parts Discussed in Thread: OPA188 Hi, we have design a board that use ADS1258 ADC to convert 8 differential channel.
We have a problem only when we use channel 0 and channel 7 together.
We have wired on channel 0 a load…
Hi Joseph，
I use the DAC outputs.
And I have been changed the output voltage of DAC outputs to -5V ~ +5V with OPA188 according to the note.
The TINA file is below, please help me to check it.

Hello Hardik,
The op amp should have low offset and low offset drift, and be usable with the +15 V single supply. Take a look at the OPA188. I think it will do what you need:

Part Number: DAC8760 Other Parts Discussed in Thread: OPA188 , hello！
Please tell me, DAC8760 reference design recommended circuit, voltage and current output are connected together, OPA188A needs to be added in Vsense+. If the output voltage and current…
Hello Krishna,
Thank you for your post. I have done this for you already for:
VIN = 0-10V
IOUT = 0-1024uA

Hello Meng,
Op amp voltage noise density (e n ) is roughly inversly related to the operating current. If you need lower noise than the OPA140, or OPA188, then you likely will need to accept higher operating current. There are bipolar input op amps with…
Thank yoy , Joseph for your reply. I am still puzzled. I came across a very nice example which I hoe will work with the TI components as well. Can you please comment. I hope it is readable, as I could not find a way to add file.
Note; Iout and Vout…
Part Number: LMP2232 Other Parts Discussed in Thread: OPA188 , LMP2234 , LMP2231 , Hi TI Experts,
Can you tell me if this amplifier LMP223x is auto-zero device implementing a chopper scheme?
We have a customer designing a noise sensitive sensor…
Hello,
I believe the issue your customer is facing with the TLV171 model is related to this forum thread . The TLV171 and the OPA188 both use the same model architecture so I am confident the issues are related.
Thank you,
