How it works

A simple 8 bit R2R DAC. Driven externally or by an OpenLane generated sawtooth waveform generator.

How to test

Drive externally

Set the external data input high to provide the DAC with external data. Then drive the 8 inputs and observe the analog output.

Drive with internal sawtooth wave generator

Set the external data input low to enable the sawtooth generator. A sawtooth wave should be seen on the analog output.

To change the frequency, set the inputs and then raise the 'load divider' input.

External hardware

A multimeter to measure the output voltage on analog pin 0.
