SGM8473
Rail-to-Rail Output, High Input Impedance, Low Power, Low Noise Difference Amplifier
The SGM8473 series is a high accuracy, high voltage, low power, low noise and high input impedance difference amplifier, which is designed to offer fixed gain options of 0.2V/V and 0.6V/V by using integrated resistors. The device works well in battery-powered applications due to the low power consumption of 1.3mA typical quiescent current.
The SGM8473 provides 70ppm (MAX) non-linearity. SGM8473A1 offers 1.5mV (MAX) low input offset voltage and SGM8473A3 offers 1.2mV (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 SGM8473A1 offers 120nV/√Hz noise, 300fA/√Hz low input voltage input current noise at 1kHz, and 9μVP-P in the 0.1Hz to 10Hz band. The SGM8473A3 offers 80nV/√Hz low input voltage noise, 300fA/√Hz input current noise at 1kHz, and 6μVP-P in the 0.1Hz to 10Hz band. They are suitable for pre-amplifier applications. The 10μs settling time to 0.1% makes SGM8473 appropriate for multiplexed applications.
The SGM8473 series is available in a Green SOIC-8 package. It is specified over the extended -40℃ to +125℃ temperature range.
