2.3.2 DAC

The Digital-to-Analog Converter (DAC) converts a digital value to a voltage. ATtiny817 features an 8-bit Resistor String type DAC, capable of converting 350,000 samples per second (350ksps), with the internal Voltage Reference (VREF) as upper limit for conversion. The DAC has one continuous time output with high drive capabilities, which is able to drive a 5kΩ or 50pF load. The DAC has one analog output pin (DACOUT), namely the PA06, that must be configured before it can be used.
