Voltage Comparator (Comp_PDL)

• Low input offset
• Multiple power/speed levels
• Operates in Deep Sleep mode
• Output can be routed to digital logic blocks or device pins
• Multiple interrupt edge modes

General Description

The Voltage Comparator Component (Comp_PDL) provides a hardware solution to compare two analog input voltages. The output is sampled in software or routed to a digital Component. There are three-speed levels to allow optimizing for speed or power consumption. A reference or external voltage can be connected to either input terminals.

The input offset is designed to be less than 1 mV over temperature and voltage. The Component supports a 10 mV input hysteresis that can be enabled.

The comparator can operate in Deep Sleep mode and its interrupt can wake up the device from Deep Sleep mode.
