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
Part Number: ADS124S08 Other Parts Discussed in Thread: THP210 , , ADS127L11 , OPA2378 Tool/software: Hello,
I want to drive ADS124S08 with THP210 FDA. Can you help me defining filtering elements at the ADCs inputs for differential input.
Other Parts Discussed in Thread: OPA2388 , OPA2333 , TLV2333 , OPA2333-Q1 , OPA2378 Hi all,
I am looking for a P2P replacement of MCP6V02-E/SN.
Could I have your help here?
Thank you!
Sincerely,
Karen
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…
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…
Hi Future,
Since you have not provided detailed product design requirements, I will provide you some ideas. This is based on the information you provided so far. The following suggestion is one of the design options.
1. Please take a look at OPA378…
Feedback resistor acts as a load at the op amp's output; therefore, the higher resistor value than the typical specified in the datasheet should not be a problem; it is a lower value resistance that may be a problem if the output cannot drive it due to…
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 closed…
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…
