The SGM621A 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 SGM621A provides SOIC-8, MSOP-8 and TDFN-3×3-8L packages which are much smaller than discrete classical-three-OPAs circuits.
The SGM621A provides 120ppm (MAX) non-linearity and 80μV (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 SGM621A 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 SGM621A appropriate for multiplexed applications.
The SGM621A is available in Green SOIC-8, MSOP-8 and TDFN-3×3-8L packages. It is specified over the extended -40℃ to +125℃ temperature range.
