Single OpAmp with Class AB output stage

Category: Hardware

Hello

are there Low-Voltage, Low Ib, RR Single OpAmps with Class-AB output stage similar to OPA202 ?

Do you have LTspice model for such a type?

Thanks in advance for your help.

  • Hi ,

    I think LTC6081/LTC6082 or LTC6078/LTC6079 may be very close to OPA202 that you asked about. But they are duals and quads (not single like OPA202).

    All of these have the LTspice model readily available from within LTspice program.
