Single supply, Low Offset Operational Amplifier

Other Parts Discussed in Thread: OPA2197, TLV4171


I am looking for a single supply, low offset operational amplifier. My input is 0V to 50 milli volts AC and expected output is 0V to approx 3V to 4V.

Kindly suggest suitable Op-Amp.

Is OPA2197 a correct choice OR is TLV4171 the correct one ? Else suggest best part for the given requirements

  • There are likely many amplifiers that will work in your application depending on the desired dc performance, ac performance, cost, size, etc.  The OPA2197 is a good general purpose precision amplifier with rail-to-rail inputs/outputs, low dc offset and good load drive capabilities.
