1 ADS8555EVM-PDK Overview
This document describes how to connect the EVM to your computer and test equipment to evaluate device
performance and understand device features. The document also describes how to install and use the
associated evaluation module software.
1.1 ADS8555EVM-PDK Features
Figure 1-1
shows the proper component connection for the ADS8555EVM. The ADS8555 evaluation module kit
includes the following features:
•
Hardware and software required for diagnostic testing as well as accurate performance evaluation of the
ADS8555 ADC.
•
Digital and analog interface power with universal serial bus (USB) power. External power is required for the
high-voltage ±15-V supply.
•
Easy-to-use evaluation software for the 64-bit Microsoft
operating systems.
•
Precision host interface (PHI) controller translates the USB (2.0) or higher to parallel or serial digital
communications.

1.2 ADS8555EVM Features
•
Six input channels connected to external single-ended signals that are source applied to subminiature version
A (SMA) connectors or headers.
•
Serial and parallel interface connects to the PHI controller via a 60-pin connector (J2).
•
High-voltage power supplies (HVDD and HVSS) are not included. Connect common lab supplies via screw
terminal J1.
•
Analog low-voltage supplies (AVDD = 5 V) are generated using an external 15-V supply and a low-dropout
regulator (LDO). HVDD (12-V supply) is also generated using the 15-V supply and an LDO. HVSS (–12-V
supply) is generated using the –15-V supply and an LDO.
•
Digital low-voltage supply (DVDD = 3.3 V) is generated using USB power from the PHI controller.
•
Integrated or external voltage reference options are available.
