Overview
The AD8051ARTZ-R2, produced by Analog Devices Inc., is a high-speed, single, rail-to-rail operational amplifier. It is part of the AD8051 family, which includes the AD8052 (dual) and AD8054 (quad) amplifiers. These amplifiers are known for their low cost, high speed, and excellent overall performance, making them versatile components for various applications.
The AD8051 operates on single-supply voltages of +3 V, +5 V, or dual-supply voltages of ±5 V, with a low supply current. It features true single-supply capability with an input voltage range that extends 200 mV below the negative rail and within 1 V of the positive rail. This amplifier is particularly suited for high-speed portable equipment, video electronics, and active filter applications due to its low distortion and fast settling times.
