  RE: OPA1622: Single-Ended Input Circuit for OPA1622

  Hi Jeffrey, Thanks for your post. You can use the OPA1622 in a single-ended application. I would recommend that the DC resistance at both op amp inputs is matched so that the bias current of the amplifier doesn't create too much offset at the output...

  RE: OPA1622: Noise in output during shutdown.

  Hi William, The input voltage noise in any op amp is an inverse function of Itail current biasing the input differential pair: Vnoise~1/Itail. Therefore, it should come as no surprise that as the part gets shutdown, Itail goes down and thus voltage...
