Part Number: OPA2391 Other Parts Discussed in Thread: TLV8542 Tool/software: Hello
We are targeting to use the TLV8542 or the OPA2391 into our design to interface a high impedance accumulator (>100 mega ohm impedance accumulator)
when our device is…
You cannot measure current at 50pA level with a chopper amplifier like OPA2333 because of its relatively high IB (max 200pA). For this reason, you need to use a linear amp with a very low IB like OPA2391 and calibrate the initial Vos and IB error.
Below…
Part Number: OPA2387 Other Parts Discussed in Thread: OPA387 , ADS1299 , OPA397 , OPA2392 , OPA2376 , OPA2391 , TLV2376 Tool/software: Hello,
we are designing a EEG Device ,where the device is suitable for EEG device as pre amplifier in AFE. And also please…
Paul,
You probably want to build the input stage discretely if you want higher transimpedance gain. Instrumentation amplifiers normally have relatively low feedback resistors to minimize thermal noise for the typical voltage amplifier use case. You could…
Part Number: OPA188 Other Parts Discussed in Thread: OPA197 , OPA333 , OPA2387 , OPA2197 , OPA2192 , OPA2391 , OPA2392 , OPA2191 the following curcuit is a constane current circuit. and the output current range is 200nA to 4uA. we found that the circuit will…
