Introduction

AI Translation

The AD8021 is an exceptionally high performance, 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 (2.1 nV/√Hz typical and 2.1 pA/√Hz typical) while operating at the lowest quiescent supply current (7 mA @ ±5 V) among today’s high speed, low noise op amps. The AD8021 operates over a wide range of supply voltages from ±2.25 V to ±12 V, as well as from single 5 V supplies, making it ideal for high speed, low power instruments. An output disable pin allows further reduction of the quiescent supply current to 1.3 mA. The AD8021 allows the user to choose the gain bandwidth product that best suits the application. With a single capacitor, the user can compensate the AD8021 for the desired gain with little trade-off in bandwidth. The AD8021 is a well-behaved amplifier that settles to 0.01% in 23 ns for a 1 V step. It has a fast overload recovery of 50 ns. The AD8021 is stable over temperature with low input offset voltage drift and input bias current drift, 0.5 μV/°C and 10 nA/°C, respectively. The AD8021 is also capable of driving a 75 Ω line with ±3 V video signals. The AD8021 is both technically superior and priced considerably less than comparable amps drawing much higher quiescent current. The AD8021 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. The AD8021 is available in both standard 8-lead SOIC and MSOP packages in the industrial temperature range of -40°C to +85°C.
