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 6.6nV/Hz input voltage noise and 0.2μVpp noise from 0.1Hz to 10Hz.
The XR620A 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 XR620A also features 50ppm maximum nonlinearity. These features make it well suited for use in data acquisition systems.
