SGM8716A-1

The SGM8716A-1 and SGM8716B-1 are single, micro-power, small size comparators. They are optimized for low voltage operation from 1.6V to 5.5V single supply, and support rail-to-rail input operation. The SGM8716A-1 and SGM8716B-1 consume only 5.5μA quiescent current. Meanwhile, they also have a great trade-off between low power and high speed, with a low propagation delay of 290ns. This results in continuous system monitoring and quick respond to fault conditions without excessive battery power dissipation. 

These devices have different output structures. The SGM8716A-1 has an open-drain output structure, which requires an external pull-up resistor to output a high level of VS or a voltage below V_S. This enables conversion from bipolar to single-ended signals and level translation. The SGM8716B-1 has a push-pull output structure, which can easily drive LEDs, resistive or capacitive loads with the ability to source or sink current at the milliamp level. 

The SGM8716A-1 and SGM8716B-1 are designed with internal hysteresis and prevent output phase reversal when the inputs are overdriven. Therefore, these comparators are capable of transforming slow-moving input signals into clear digital outputs and monitoring voltage in noisy and demanding settings. 

The SGM8716A-1 and SGM8716B-1 are both available in a Green SOT-23-5 package. They are rated over the -40℃ to +125℃ operating temperature range.
