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 5.6mA supply current. At unity-gain, the OPA820 gives > 800MHz bandwidth with < 1dB peaking. The OPA820 complements this high-speed operation with excellent DC precision in a low-power device. A worst-case input offset voltage of ±750µV and an offset current of ±400nA give excellent absolute DC precision for pulse amplifier applications.

Minimal input and output voltage swing headroom allow the OPA820 to operate on a single +5V supply with > 2V_PP output swing. While not a rail-to-rail (RR) output, this swing will support most emerging analog-to-digital converter (ADC) input ranges with lower power and noise than typical RR output op amps.
