XR620A

Instrumentation Amplifier

FEATURES

ꢀ■

General Description

2.3ꢀ to 18ꢀ supply voltage range

ꢀ■

Gain range of 1 to 10,000

Gain set with one external resistor

125μꢀ maximum input offset voltage

0.1μꢀ/°C input offset drift

700kHz bandwidth at G = 1

1.2ꢀ/μs slew rate

90dB minimum CMRR at G = 10

The XR620A is a low power, general purpose instrumentation ampliﬁer

with a gain range of 1 to 10,000. The XR620A is offered in 8-lead SOIC or

DIP packages and requires only one external gain setting resistor making

it smaller and easier to implement than discrete, 3-amp designs.

ꢀ■

While consuming only 2.2mA of supply current, the XR620A offers a low

6.6nꢀ/Hz input voltage noise and 0.2μꢀpp noise from 0.1Hz to 10Hz.

ꢀ■

2.2mA maximum supply current

6.6nꢀ/√Hz input voltage noise

70nꢀ/√Hz output voltage noise

0.2μꢀ_ppinput noise (0.1Hz to 10Hz)

The XR620A offers a low input offset voltage of 125μꢀ that only varies

0.1μꢀ/°C over it’s operating temperature range of -40°C to +85°C. The

XR620A also features 50ppm maximum nonlinearity. These features

make it well suited for use in data acquisition systems.
