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
6.6nV/Hz input voltage noise and 0.2μV_pp noise from 0.1Hz to 10Hz.
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.
