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
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.

... CADEKA Microcircuits LLC Medical ECG The CLC1201 is perfect for ECG monitors because of its low current noise. A typical applicaiton is shown in Figure 4. The CLC1201’s low power, low supply voltage requirements, and space-saving 8-lead SOIC package offerings make it an excellent choice for battery-powered data recorders. ...

... Data Sheet Grounding The output voltage of the CLC1201 is developed with respect to the potential on the reference terminal (pin 8). Simply tie the REF pin to the appropriate “local ground” to resolve many grounding problems. To isolate low level analog signals from a noisy digital environment, many data-aquisistion components have separate analog and digital ground pins ...
