General Description

The CLC1201 is a low power, general purpose instrumentation amplifier with

a gain range of 1 to 10,000. The CLC1201 is offered in 8-lead SOIC or DIP

packages and requires only one external gain setting resistor making it small-

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

While consuming only 2.2mA of supply current, the CLC1201 offers a low

The CLC1201 offers a low input offset voltage of ±125μV that only varies

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

CLC1201 also features 50ppm maximum nonlinearity. These features make it

well suited for use in data acquisition systems.
