Pmod R2R: 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“ × 0.8” (2.54 cm × 2.0 cm)

• 2×6-pin Pmod connector with GPIO interface

• Follows Digilent Interface Specification Type 1

What's Included:

• Pmod R2R
• Custom antistatic Pmod packaging
