GENERAL DESCRIPTION

 

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.
