6.2.2 Enable-Status (E/S) Pin

The enable-status (E/S) pin provides two unique functions:

  1. Output disable by forcing the pin LOW
  2. Thermal shutdown indication by monitoring the voltage level at the pin
One or both of these functions can be used on the same device. For normal operation (output enabled), pull the E/S pin high (at least 2 V greater than V−). A small-value capacitor can be connected between the E/S pin and V− for noisy applications. To enable the OPA561 permanently, tie the E/S pin to V+ through a 402‑kΩ pullup resistor.
