Figure 26-2. DAC output model
Notes:
The DAC is clocked from the Peripheral clock (clk
refresh rate in S/H mode is configured relative to the Peripheral Clock.
Some timing constraints are given to make sure the DAC operates correctly. The timing con-
straints are relative to the frequency of the Peripheral clock. Not meeting the timing constraints
may reduce the accuracy of DAC conversions.
To reduce the power consumption in DAC conversions, the DAC may be set in a Low Power
mode. In Low Power mode, the DAC is turned off between each conversion. Conversion time
will be longer if new conversions are started in this mode. To put the DAC into low power mode,
you need to set the bit 1 in CTRLA register (called DACCRA).
To achieve optimal accuracy, it is possible to calibrate both gain and offset error in the DAC.
There is a 7-bit calibration value for gain adjustment and a 7-bit calibration value for offset
adjustment.
To get the best calibration result it is recommended to use the same VREF, output channel
selection, sampling time, and refresh interval when calibrating as will be used in normal DAC
operation. The theoretical transfer function for the DAC was shown in
Including errors, the DAC output value can be expressed as:
In an ideal DAC, gain is 1 and offset is 0.
