Digital-to-analog converter (DAC)

Overview
The Digital-to-analog converter converts 10-bit digital data to a voltage on the external pins. The output voltage can be optionally buffered for higher drive capability. The two DACs can work independently or concurrently.
DAC main features
(1) Two DAC converters: one output channel each
(2) Conversion triggered by external triggers
(3) Dual DAC channel independent or simultaneous conversions
(4) Configurable internal buffer
(5) External triggers for conversion
(6) Input voltage reference VREFP

DAC characteristics

DAC output voltage
The analog output voltage on the DAC pin is determined by the following equation:
DACoutput = VREFP ∗ DAC_Dout/1024
The digital input is linearly converted to an analog output voltage, its range is 0 to VREFP。
