ADA4522

Analog Devices · Operational Amplifier · SOIC-8

The ADA4522-1 is a single zero-drift operational amplifier that pairs low input offset (5 uV max) and near-zero drift with a wide supply range up to 55 V and low broadband noise. Its combination of precision and high-voltage operation suits demanding bridge, current-sense, and instrumentation front ends that run from higher rails.

Pinout

Pin	Name	Type	Function
1	NIC	unconnected	Not internally connected. Leave floating or optionally tie to a stable potential; no internal die connection.
2	-IN	input	Inverting input of the op amp. Ground-sensing input; input voltage range extends from V- (ground on single supply) to (V+) - 1.5 V.
3	+IN	input	Noninverting input of the op amp. Ground-sensing input; input voltage range extends from V- (ground on single supply) to (V+) - 1.5 V.
4	V-	power_in	Negative supply voltage. Single-supply operation: connect to GND (V+ = 4.5 V to 55 V). Dual-supply operation: -2.25 V to -27.5 V referenced to ground.
5	NIC	unconnected	Not internally connected. Leave floating or optionally tie to a stable potential; no internal die connection.
6	OUT	output	Op amp output. Rail-to-rail output; drives 10 kΩ loads to within millivolts of either supply rail.
7	V+	power_in	Positive supply voltage. Total supply range 4.5 V to 55 V (single) or ±2.25 V to ±27.5 V (dual). Bypass with a local 0.1 µF ceramic to V-/GND close to the pin.
8	NIC	unconnected	Not internally connected. Leave floating or optionally tie to a stable potential; no internal die connection.
