Part Number: OPA2378 Hi team,
Please let us know the chopping frequency of OPAx378, since its input charge injection is concerned.
Best regards, Iwata Etsuji

I am looking for a P2P replacement of MCP6V02-E/SN.
Could I have your help here?
Thank you!
Sincerely,

Originally, we had an option of designing the circuit with either OPA2378 or MCP6V02. However, the OPA2378 is out of stock. I have not got response from Microchip yet. If MCP6v02 needs to be replaced, I can do it. I have already been changing parts for…

I have cost issue,so I can not use 25 transimpedance amp circuit.
Could I use analog switch to switch…
Ok here are some guesses,
I went to the 900kHz OPA2378 dual, another RRIO chopper - plenty fast but higher noise,
Here is what I mean about biasing. Just use a single supply and apply the max ADC input voltage to the + input - then, if the current flows…

I am looking for an opamp for low frequency (up to 1MHz) which can do the below operation.
I need two opamps in one package.
The OPA2835 is a candidate…
Hello Dany,
I have attached a PowerPoint of the analysis and recommendations to this response. Thank you for your patience.
Best,

TG,
First, I don't think it's a typo. Figure 17 pretty clearly shows about 230ohms of output impedance.
How much output impedance and what frequency are you looking for? It looks like OPA2378 would be better, but I don't know how to compare…
Tony,
The op-amp is connected as a voltage follower, with a 0.1u capacitor at the output to maintain stability.
Do you mean I have to measure the offset of the op-amp manually and hard-coded my program to subtract that value to all my measurements…
