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 aquisition systems.
