GENERAL DESCRIPTION

The SGM620 is a high accuracy, high voltage instrumentation amplifier, which is designed to set any gain from 1 to 10000 with one external resistor. The device works well in battery-powered applications due to the low power consumption of 1.3mA typical quiescent current. The SGM620 provides a SOIC-8 package which is much smaller than discrete classical-three-OPAs circuits.

The SGM620 provides 120ppm (MAX) non-linearity and 150μV (MAX) low input offset voltage. The device also features low noise, low bias current and low power. The combination of these characteristics makes it a good choice for applications requiring excellent DC performance.

The SGM620 offers 6nV/√Hz low input voltage noise, 300fA/√Hz input current noise at 1kHz, and 0.4μVP-P in the 0.1Hz to 10Hz band. It is suitable for pre-amplifier applications. The 10μs settling time to 0.01% makes SGM620 appropriate for multiplexed applications.

The SGM620 is available in a Green SOIC-8 package. It is specified over the extended -40 to +125 temperature range.
