Chapter 1 EVM Overview This chapter provides an overview of the DAC7574, DAC6574, DAC5574, DAC7571, DAC6571, DAC5571, and DAC8571 evaluation module (EVM), and instructions on setting up and using this module. Topic Page Features ........... . . -
Page 10: Features
Features 1.1 Features This EVM features the DAC7574, DAC6574, DAC5574, DAC7571, DAC6571, DAC5571, and DAC8571 digital-to-analog converter (DAC). It provides a quick and easy way to evaluate the functionality and performance of the high-resolution as well as the low - resolution I C-input DACs. -
Page 11: Power Requirements
Power Requirements 1.2 Power Requirements The following sections describe the power requirements of this EVM. 1.2.1 Supply Voltage The dc power supply for the digital section (V ) of this EVM is selected between 3.3 V and 5 V via the 3-position jumper W14. The digital power connects to the J5- 1, J6 - 9, or J6 - 10 terminal (when plugged in with another EVM board or interface card) and is referenced to ground through the J5 - 2 and J6- 5 terminals. -

Page 16: Pcb Layout
PCB Layout 2.1 PCB Layout The DAC EVM demonstrates the high performance of the DAC under test conditions specified in the datasheet by implementing design practices that preserve DAC performance. Careful analysis of these practices is the key to a successful design implementation. Many of the practices affect the schematic design phase, including correct component selection, adequate bypassing, separating and managing analog and digital signals, and understanding component mechanical attributes. -
