The F1680 includes an eight-channel Successive Approximation Register Analog-to-Digital Converter (SAR ADC). This ADC features 8 Analog input sources multiplexed with general-purpose I/O ports, a fast conversion time of 4.9 μs, programmable timing controls, and an internal 1.6 V voltage reference generator. This series also features two general-purpose comparators and a Low-Power-Operational amplifier (LPO) for use in current sense applications with an output that can be internally routed to the ADC or externally to a pin.
