1 EVM Overview

The ADS1263EVM is a platform for evaluating the performance of the ADS1263, a 32-bit, 38-kSPS, 10-channel
(multiplexed), ΔΣ ADC. The evaluation kit includes the ADS1263EVM board and the precision host interface
(PHI) controller board that enables the accompanying computer software to communicate with the ADC over
USB for data capture and analysis. The ADS1263EVM board includes the ADS1263 as well as the high-
performance peripheral analog circuits necessary to extract optimum performance from the ADC. The PHI board
primarily serves three functions:
• Provide a communication interface from the EVM to the computer through a USB port
• Provide the digital input and output signals necessary to communicate with the ADS1263
• Supplies power to all circuitry on the ADS1263EVM board

1.1 ADS1263EVM Kit

The ADS1263 evaluation kit includes the following features:
• Hardware and software required for diagnostic testing as well as accurate performance evaluation of the
ADS1263 ADC.
• USB powered: No external power is required.
• PHI controller that provides a convenient communication interface to the ADS1263 ADC over USB 2.0 (or
higher) for power delivery as well as digital input and output.

• Microsoft Windows
• Easy-to-use evaluation software for 64-bit Microsoft Windows.
• The software suite includes graphical tools for data capture, histogram analysis, and spectral analysis. This
suite also has a provision for exporting data to a text file post-processing.

1.2 ADS1263EVM Board

The ADS1263EVM board includes the following features and options:
• Ultra-low noise TPS7A4700, low-dropout (LDO) linear regulator supplies 5-V ADC analog voltage (AVDD), or
use an external voltage supply
• 3.3-V ADC digital voltage (DVDD) supplied by PHI controller, or use external voltage supply
• Test points for power, GND, reference, and all digital signals to and from the PHI controller
• Optional external clocking and voltage reference footprints
