The Makerverse™ 10-bit R2R Digital to Analogue Converter (DAC) is a simple and effective way to turn a digital signal into an analogue signal - featuring high accuracy 0.1% resistors and an op-amp voltage buffer. To see (and hear!) it produce music and sound effects, see the Makerverse Audio Kit Guide.
This DAC has been specifically designed for connecting to a Raspberry Pi Pico - the pins and labels are arranged to make it very intuitive to connect - but can be driven by any digital circuit you desire.
The Makerverse 10-bit R2R DAC is based on a simple R2R Resistor Ladder which is a great way to study how a DAC works. It has a THD+N (total harmonic distortion plus noise) specification of approximately 60dB - very close to the theoretical limit for a 10-bit converter and capable of reproducing clear audio signals.
The onboard voltage buffer op-amp is a "rail-to-rail" type, allowing for the DAC module to operate from either 3.3V or 5.0V with only 25mV of clipping when the output approaches the supply rails. The true operating voltage range is 1.8V to 6.0V so the DAC module itself is compatible with other microcontrollers.
The digital inputs labelled GP6 (LSB) to GP15 (MSB) form the binary input with the 0 to 1023 input range mapping linearly from 0V to 3.3V with a step size of approximately 3.2mV.
If you are applying this module to a different microcontroller, and don't need the full 10-bit resolution, only the highest numbered inputs need to be connected and unused inputs connected to ground. For example, a 5-bit DAC can be built by driving GP15 to GP11 with digital signals and grounding GP6 to GP10.
