OPA820ID

产品概述

The OPA820ID is an unity-gain stable voltage-feedback Operational 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 >2VPP 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. Exceptionally low dG/dP (0.01%/0.03°) supports low-cost composite video line driver applications.
