John,
Yes, the OPA4277 is a good choice. Both devices have good offset, and offset drift. The OPA4277 is a bipolar device, and the OPA188 is a chopper CMOS amplifier. The key characteristic on chopper amplimers is that they have good offset and offset…
Part Number: OPA4277 Other Parts Discussed in Thread: OPA4227 hello.
I'm using the operational opa2477. I am using it within a circuit to adjust the gain of a signal. The amplifier gets very hot, so I remove all the components that connect it with the…
