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 in storage mode, the amplifier is not powered,
we use is as a non inverting amplifier with unity gain to buffer the signal into our system, the accumulator (+/-0,3VDC) is directly connected to the IN+ of the amplifier,
please can you share data about the capabilities of the TLV8542 and the OPA2391 to maintain the performances on the bias current when the device is not powered
looking forward for your support
best regards
