Overview
Engineered around the Analog Devices
AD5628 Digital to Analog Converter, the
Digilent PmodDA4 provides 8 channels of D/A
conversion at 12 bits of resolution. The
PmodDA4 can be used with Digilent system
boards as well as a growing number of third-
party boards equipped with Digilent Pmod
connectors.
Features include:
Analog Devices AD5628 low power,
octal, 12-bit, buffered voltage-output
DAC
High-speed DSP compatible
Low power consumption
Power-down function capability
6-pin Pmod connector with 3-wire
Serial interface
12-pin output connector
Functional Description
The PmodDA4 can produce an analog output
ranging from 0V to 2.5V when operated with a
3.3V power supply. It has eight D/A conversion
channels, each with a 12-bit converter that can
process separate digital signals.
To produce outputs, simply send commands to
the eight D/A converters via the SPI serial bus.
(Note: Always send this SPI data to the device
as a 32-bit word.) You can send D/A converter
settings to individual D/A converters or all eight
D/A converters at once.
For a description of the signals on the interface
connectors J1 and J2, see Table 1. For more
detailed information, users should refer to the
PmodDA4 schematic available on the Digilent
web site.
