Part Number: OPA928EVM Other Parts Discussed in Thread: OPA928 , OPA3S328 Tool/software: I want to use an OPA928EVM and I want to change the Rf resistor depending on the situation. There are only two jumpers and no switching switch, and one of them has…
Part Number: LMC6482 Other Parts Discussed in Thread: OPA928EVM , OPA928 Tool/software: Hi Sir,
In current measurement application (precision is 1 pA), the LMC6482 has a high response time. Could you please recommend an integrator op-amp IC with similar…
Hi Lauren,
LAURENT IFERGANE said: What photodiode reference would you recommend?
In terms of TIA reference design, here are two TIA reference design. Also I included OPA928EVM reference design.

Part Number: LMP7721 Other Parts Discussed in Thread: OPA928 , OPA928EVM Hi,
I'm working on a sensor application using a photodiode connected to a transimpedance amplifier with a 5 Gigaohm feedback resistor.

Other Parts Discussed in Thread: INA190 , OPA928 , OPA928EVM , LOG114 I have a low current measurement application, for which I'm thinking about using a TI current sense amplifier (or simply an op-amp, but I've recently learned why that may not be prudent…
Rakesh,
There are 892 different op amp models that could measure nano-amps of current. Basically, any CMOS or JFET device will have picoamps of bias current, so they can measure nano-amps. You should avoid bipolar as they will have nano-amps of bias…
Hi Kai
I am sorry i do not agree with your response.
Foremost, the product is showing to be CE marked. When the manufacturer applies CE to their product, they must issue the EU Declaration of Conformity for that product. This is a legal requirement…
Part Number: LMP7721 Other Parts Discussed in Thread: TINA-TI , OPA210 , OPA928 , OPA928EVM Hello,
I am not an electrical engineer but a chemical one. Therefore, my question is probably foolish/basic.
I would like to build a circuit that is able to…
