PmodR2R: Resistor Ladder D/A Converter

The Pmod R2R is resistor ladder with a R-2R resistor configuration. Users can provide 8-bits of parallel data to the module through GPIO signals. This setup teaches users the basic principles behind a Digital-to-Analog Converter. Features: 8-bit digital-to-analog conversion Convert data at up to 25MHz Easy attachment of oscilloscopes to illustrate the data conversion process Small PCB size for flexible designs 1.0 in x 0.8 in (2.54 cm x 2.0 cm) 2x6-pin Pmod connector with GPIO interface Follows Digilent Interface Specification Type 1 Specs Datasheet
