Hi team,

The customer would like to get the internal schematic of the OPA4277 device.

    Mickey,
    The short answer is no. In line with the TI internal policy, we do NOT share our products internal schematics with our clients irrespective of NDA agreements. All I can tell you is that OPA4277 is fabricated on an old Burr-Brown bipolar process and its circuit topology resembles OPA4132 but with its JFET differential pair being replaced with bipolar diff pair that includes input bias current cancellation circuitry.
