DAC63204EVM

This user’s guide describes the characteristics, operation, and use of the DAC63204EVM evaluation module (EVM). This EVM is designed to evaluate the performance of the DAC63204, DAC53204, and DAC43204 (DACx3204) commercial, buffered voltage output DACs in a variety of configurations. Throughout this document, the terms evaluation board, evaluation module, and EVM are synonymous with the DAC63204EVM. This document includes a schematic, printed-circuit board (PCB) layouts, and a complete bill of materials.

1 Overview

The DAC63204EVM is an easy-to-use platform to evaluate the functionality and performance of the DAC63204, DAC53204, and DAC43204 commercial devices.

The 12-bit DAC63204, 10-bit DAC53204, and 8-bit DAC43204 (DACx3204) are a pin-compatible family of quad-channel, buffered, voltage-output and current-output smart digital-to-analog converters (DACs). The DAC outputs are capable of both voltage and current output. The DACx3204 support Hi-Z power-down mode and Hi-Z output during power-off conditions. The DAC outputs provide a force-sense option for use as a programmable comparator and current sink. The multifunction GPIO, function generation, and nonvolatile memory (NVM) enable these smart DACs for use in applications and design reuse without the need for a processor (processorless operation). These devices also automatically detect I2C, SPI, and PMBus interfaces, and contain an internal reference.

2. Detailed Description

shows a simplified schematic of the DAC63204EVM board. There are two 16-pin connectors that provide access to all of the DAC pins. The GPIO, I2C, and SPI signals from the onboard controller are connected to the DAC through three level translators. Each level translator can be independently disabled to disconnect the onboard controller GPIO, I2C, and SPI signals from the DAC signals while the DAC is running in stand-alone mode.
