Product Overview

The AD8021ARZ is a Low Noise High Speed Voltage Feedback Amplifier that can be used in 16-bit resolution systems. It is designed to have both low voltage and low current noise (2.1nV/√Hz typical and 2.1pA/√Hz typical) while operating at the lowest quiescent supply current (7mA at ±5V) among today's high speed, low noise op amps. An output disable pin allows further reduction of the quiescent supply current to 1.3mA. The AD8021 allows the user to choose the gain bandwidth product that best suits the application. It is also capable of driving a 75Ω line with ±3V video signals. The AD8021 is both technically superior and priced considerably less than comparable amps drawing much higher quiescent current. It is a high speed general-purpose amplifier, ideal for a wide variety of gain configurations and can be used throughout a signal processing chain and in control loops.
