General Description

The OPA820 provides a wideband, unity-gain stable, voltage-feedback amplifier with a very low input noise voltage and high output current using a low 6.8-mA supply current.

The OPA820 complements this high-speed operation with excellent DC precision in a low-power device.

A worst-case input offset voltage of ±3.5 mV and an offset current of ±700 nA give excellent absolute DC precision for pulse amplifier applications.

Key Features
