    Hi, Can you describe how you replaced the amplifier? The OPA2828 is a 8 pin HVSSOP, and the TPA2681 is a 5 pin SOT23. Are you just using wires to connect the pins? Please make sure: DAC IOUT is connected to TPA pin 4 (-In) GND is connected to TPA pin 3 (+In…

    Thanks for the reply Art. Art Kay said: Mismatch of the resistors and capacitors on the first stage could cause system CMRR issues. This is still one of our hypotheses. And the observation that stacking the resistor network improved the CMRR by nearly…

  • RE: OPA2210: Similar spec part, with higher slew rate

    In addition to OPA2211, you could also consider OPA2828 with slew rate of 150V/us. If offset and drift are also critical, OPA2189 chopper with max offset of +/-3uV and drift +/-0.02uV/C could also be a good choice.
