Unity-gain crossover: 3 MHz
Single-supply operation: input voltage range includes
ground and rail-to-rail output
Wide range of operating voltages
Single-supply operation: 4.5 V to 55 V
Dual-supply operation: ±2.25 V to ±27.5 V
Integrated EMI filters
Unity-gain stable The ADA4522-2-KGD is a dual channel, zero drift op amp with
low noise and power, ground sensing inputs, and rail-to-rail
output, optimized for total accuracy over time, temperature,
and voltage conditions. The wide operating voltage and
temperature ranges, as well as the high open-loop gain and
low dc and ac errors make the device well suited for amplifying
small input signals and for accurately reproducing larger
signals in a wide variety of applications. APPLICATIONS …
