8.3.1 Digital-to-Analog Converter Architecture
The DACx1001 provide 20-bit monotonic outputs using an R2R ladder architecture. The DAC output ranges between VREFNF and VREFPF based on the 20-bit DAC data, as described in Equation 1:
- CODE is the decimal equivalent of the DAC-DATA loaded to the DAC.
- N is the bits of resolution; 20 for DAC1101A, 18 for DAC91001, 16 for DAC81001.
- VREFPF, VREFNF is the reference voltage (positive and negative).
