SGM8756

The SGM8756 is a single, low power comparator with a precision voltage reference. It is optimized for low voltage operation from 2.5V to 5.5V single supply, and consumes only 40µA supply current. These two advantages make the device a good choice for portable and battery- powered equipment. Meanwhile, the SGM8756 has a great trade-off between low power and high speed, whose propagation delay is only 280ns with 100mV overdrive. 

The SGM8756 supports rail-to-rail input and output operation. The input common mode voltage range is from -V_S to +V_S. The device has an input offset voltage of ±3mV (MAX) and an input bias current of ±0.1nA (TYP). The SGM8756 has a push-pull output structure, which is capable of sinking and sourcing milliamps of current. The comparator output structure is specially designed to decrease the surges of supply current during switching. It can sufficiently reduce the overall power consumption in dynamic states, and almost eliminate many common power faults found in other comparators. The SGM8756 has an internal hysteresis for reducing comparator sensitivity to noise, even when the input signals move slowly. 

The SGM8756 integrates a 1.23V voltage reference. The voltage reference features a low temperature drift of 100ppm/℃ (MAX) and a high accuracy of ±0.4% (MAX). 

The SGM8756 is available in a Green WLCSP-1.4×0.9-6B package. It is specified over the operating temperature range of -40℃ to +125℃.
