OPA820 Overview
Description
The OPA820 device provides a wideband, unity-gain stable, voltage-feedback amplifier with a very-low input-noise voltage and high-output current using a low 5.6-mA supply current. At unity-gain, the OPA820 device gives more than 800-MHz bandwidth with less than 1-dB peaking.
