The SGM621E 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 SGM621E provides SOIC-8 and MSOP-8 packages which are much smaller than discrete classical-three-OPAs circuits.
The SGM621E provides 140ppm (MAX) non-linearity and 55μV (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 SGM621E offers 6nV/√Hz 300fA/√Hz low input voltage noise, 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 SGM621E appropriate for multiplexed applications.
The SGM621E is available in Green SOIC-8 and MSOP-8 packages. It is specified over the extended -40℃ to +125℃ temperature range.
