ꢀ■
Gain range of 1 to 10,000
Gain set with one external resistor
125μ3 maximum input offset voltage
0.1μ3/°C input offset drift

The CLC1200 is a low power, general purpose instrumentation amplifier
with a gain range of 1 to 10,000. The CLC1200 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, ꢀ-amp designs.

While consuming only 2.2mA of supply current, the CLC1200 offers a low
6.6n3/Hz input voltage noise and 0.2μ3pp noise from 0.1Hz to 10Hz.

6.6n3/√Hz input voltage noise
70n3/√Hz output voltage noise
0.2μ3pp input noise (0.1Hz to 10Hz)
The CLC1200 offers a low input offset voltage of 125μ3 that only varies
0.1μ3/°C over it’s operating temperature range of -40°C to +85°C. The
CLC1200 also features 50ppm maximum nonlinearity. These features
make it well suited for use in data acquisition systems.
