The following equation describes the DAC transfer function, which is the relationship between internal signal DAC_CODE and output voltage VOUT:
where
PVDD | DAC_CFG.RANGE | VOUT RANGE | FSR | VMIN |
---|---|---|---|---|
1.8 V | 0 | 0.15 V to 1.25 V | 1.1 V | 0.15 V |
1.8 V | 1 | 0.2 V to 1.0 V | 0.8 V | 0.2 V |
≥ 2.7 V | 0 | 0.3 V to 2.5 V | 2.2 V | 0.3 V |
≥ 2.7 V | 1 | 0.4 V to 2.0 V | 1.6 V | 0.4 V |
The VOUT range for the DAC is determined by DAC_CFG.RANGE bit when not in the CLEAR state. In the CLEAR state, the range is determined by DAC_CFG.CLR_RANGE bit.
