ADS8555EVM-PDK Evaluation Module
This user's guide describes the operation and use of the ADS8555 evaluation module (EVM). The ADS8555 is
a 6-channel, simultaneous sampling, 16-bit successive approximation (SAR) analog-to-digital converter (ADC).
Each input channel on the device can support true bipolar input ranges up to ±12 V. The device includes a
programmable, internally buffered voltage reverence. The ADC includes a serial programming interface (SPI)
interface and a parallel interface (word and byte mode) for data communication. Device configuration is achieved
through simple static digital input pins (hardware mode) or through communications to the SPI interface (control
register configuration in software mode). This user's guide covers the circuit description, schematic diagram, and
bill of materials for the ADS8555 circuit board. This EVM hardware and software can also be used to support
the ADS8556, ADS8557, and ADS8558 devices from this family. Other devices can be tested by desoldering the
ADC and reprogramming the EVM (see
provided later in this document.

    The ADS8555EVM is an evaluation module built using a two-board modular EVM system. One board is a digital controller (PHI), and the other board contains the ADC and associated analog circuitry. Both boards and the associated cables form the ADS8555EVM-PDK. 2.1 ADC Supply, Input, Voltage Reference, and Digital Connections Figure 2-1 shows the decoupling on AVDD, BVDD, HVDD, and HVSS and the voltage reference.
