# 8-bit DEM R2R DAC

- [Read the documentation for project](docs/info.md)

This design implements a linear 8-bit DAC suitable for dc and low-frequency inputs.  An analog voltage is produced by connecting the encoder's outputs to a modified R-2R ladder on the PCB (see External Hardware).  It achieves high-linearity by using segmented mismatch-shaping, so the DAC does not require matched resistors.  The encoder provides 1st order mismatch and quantization noise shaping.  With a clock frequency of 6.144 MHz and a lowpass filter corner of 24 kHz, the oversampling ratio (OSR) is 256.
