Microchip's ADC’s uses Successive Approximation Registers (SAR) to convert the analog input signal into a digital output code. SAR applies to the converter that uses approximation for precise conversions. The high-speed SAR ADC offers core independent features such as integrated digital comparators and oversampling filters.

High precision digital-to-analog converters (DAC’s) provide accurate conversions of digital streams to analog outputs. The DAC with slope compensation unit provides a user-defined slope which can be used to alter the DAC output. This feature is useful in applications, such as Peak Current mode control, where slope compensation is required to maintain the stability of the power supply.
