SGM8779-2
High Voltage, 2.4μA Ultra-Low Current, High Precision, Dual Differential Comparator
The SGM8779-2 series is a dual, rail-to-rail input and output, micro-power and high precision voltage comparator optimized for high voltage operation. The device can operate from 1.65V to 40V single supply or from ±0.85V to ±20V dual power supplies. The SGM8779-2 series supports rail-to-rail input while input signal range is from (-VS) - 0.3V to (+VS) + 0.3V and input common mode voltage range is from (-VS) - 0.1V to (+VS) + 0.1V. The SGM8779-2 series consumes only 2.4μA low supply current.
The SGM8779-2 series features low input offset voltage of ±2.2mV (MAX). It is suitable for applications requiring precision.
The SGM8779-2 series supports open-drain or push-pull output. The SGM8779A-2 has an open-drain output structure that needs external pull-up resistor. The SGM8779B-2 has a push-pull output structure, which is capable of sinking and sourcing milliamps of current when driving loads.
The SGM8779-2 series is available in Green SOIC-8 and MSOP-8 packages. It is rated over the -40℃ to +125℃ operating temperature range.
