OPA820IDBVRG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA820IDBVRG4 is a high-speed, unity-gain stable voltage feedback operational amplifier manufactured by Texas Instruments. It features a small-signal bandwidth of 1.8 GHz and a slew rate of 570 V/µs, enabling rapid signal processing in demanding applications. The device exhibits low input voltage noise of 1.8 nV/√Hz at 100 MHz and maintains low distortion characteristics with -88 dBc HD2/HD3 at 10 MHz into a 200Ω load. Operating within a supply voltage range of 5 V to 12 V (±2.5 V to ±6 V), it is housed in an 8-pin SOIC package.
