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 cmx 2.0 cm)
• 2×6-pin Pmod connector with GPIO interface
• Follows Digilent Interface Specification Type 1
