DAC53401EVM
1 Overview
The DAC53401EVM is an easy-to-use platform to evaluate the functionality and performance of the
DAC53401 device. The 10-bit DAC53401 and 8-bit DAC43401 (DACx3401) are a pin-compatible family of
buffered voltage-output digital-to-analog converters (DACs). These devices have nonvolatile memory
(NVM), an internal reference, and a PMBus™ compatible I
2
C interface. The DACx3401 operates with
either an internal reference or the power supply as a reference, and provides full-scale output of 1.8 V to
5.5 V. The devices communicate through the I
2
C interface. These devices support I
2
C standard mode (100
kbps), fast mode (400 kbps), and fast mode plus (1 Mbps). The DACx3401 are feature rich, and include
features such as PMBus voltage margin commands (for example, Turn On/Off, Margin High/Low, and
more), digital slew rate control, user-programmable power up to high impedance, a standalone waveform
generator (square, ramp, and sawtooth), a medical alarm tone generator (low, medium, and high priority),
and a dedicated feedback pin. The EVM provides the GPIO and I
2
C programming interface using a PC-
based graphical user interface (GUI).
