1 EVM Overview
The ADS127L11EVM is a platform for evaluating the performance of the ADS127L11, which is a 24-bit, high-
speed, wide-bandwidth ΔΣ ADC. The evaluation kit includes the ADS127L11EVM board and the precision host
interface (PHI) controller board that enables the accompanying computer software to communicate with the ADC
over the USB for data capture and analysis. The ADS127L11EVM board includes the ADS127L11 ADC and all
the peripheral analog circuits and components required to extract optimum performance from the ADC. The PHI
board primarily serves three functions:
• Provides a communication interface from the EVM to the computer through a USB port
• Provides the digital input and output signals necessary to communicate with the ADS127L11
• Supplies power to all active circuitry on the ADS127L11EVM board
1.1 ADS127L11EVM Kit
The ADS127L11 evaluation module kit includes the following features:
• Hardware and software required for diagnostic testing as well as accurate performance evaluation of the
ADS127L11 ADC
• USB powered—no external power supply is required
• The PHI controller that provides a convenient communication interface to the ADS127L11 ADC over USB 2.0
(or higher) for power delivery as well as digital input and output
• Windows® 8, and Windows® 10 operating systems
• Easy-to-use evaluation software for 64-bit Microsoft
