Description

The OPA277 unity-gain bandwidth is 1 MHz. EMIRR performance below this frequency denotes interfering signals that fall within the op amp bandwidth. 0. 20.

You will use this circuit to measure the stability of the OPA277 . 12 The OPA277 was chosen for its low VIO, low drift, and bipolar swing. This stage needs to have bipolar swing about ground because the input signal is bipolar.
