AD8021ARZ-REEL

AD8021 is an exceptionally high performance, high speed voltage feedback amplifier that can be used in 16bit 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. It operates over a wide range of supply voltages from ±2.25V to ±12V, as well as from single 5V supplies, making it ideal for high speed, low power instruments. An output disable pin allows further reduction of the quiescent supply current to 1.3mA. This device allows the user to choose the gain bandwidth product that best suits the application. It is used in applications such as ADC preamps and drivers, instrumentation preamps, active filters, portable instrumentation, line receivers, precision instruments, ultrasound signal processing, high gain circuits.
