PSoC™ 4 Voltage Comparator
The Voltage Comparator Component gives you a hardware solution to compare two analog input voltages. You sample the output in software or routed to a digital component. There are three speed levels to allow you to optimize for speed or power consumption. You can also connect a reference or external voltage to either input.
The input offset is designed to be less than 1 mV over temperature and voltage. The hysteresis is selectable between 10 mV and no hysteresis.
