For use with a computer, the ADS1015EVM-PDK or ADS1115EVM-PDK is available. This kit combines
the ADS1015/ADS1115EVM board with the MSP430-based MMB3 motherboard, and includes ADCPro
™
software for evaluation.
The MMB3 motherboard allows the ADS1015/ADS1115EVM to be connected to the computer via an
available USB port. This manual shows how to use the MMB3 as part of the
ADS1015EVM-PDK/ADS1115EVM-PDK, but does not provide technical details about the MMB3 itself.
ADCPro is a program for collecting, recording, and analyzing data from ADC evaluation boards. It is based
on a number of plug-in programs, so it can be expanded easily with new test and data collection plug-ins.
The ADS1015EVM-PDK/ADS1115EVM-PDK is controlled by a plug-in running in ADCPro. For more
information about ADCPro, see the
Analog-to-Digital Converter Evalutation Software User
(literature number
), available for download from the TI web site.
This manual covers the operation of both the ADS1015/ADS1115EVM and the
ADS1015EVM-PDK/ADS1115EVM-PDK. Throughout this document, the abbreviation EVM and the term
evaluation module are synonymous with the ADS1015/ADS1115EVM. For clarity of reading, the rest of
this manual will refer only to the ADS1115EVM or ADS1115EVM-PDK, but operation of the EVM and kit
for the ADS1015 is identical, unless otherwise noted.
1.2
Introduction
The ADS1115EVM is an evaluation module built to the TI Modular EVM System specification. It can be
connected to any modular EVM system interface card.
The ADS1115EVM is available as a stand-alone printed circuit board (PCB) or as part of the
ADS1115EVM-PDK, which includes an MMB3 motherboard and software. As a stand-alone PCB, the
ADS1115EVM is useful for prototyping designs and firmware.
Note that the ADS1115EVM has no microprocessor and cannot run software. To connect it to a computer,
some type of interface is required.

Analog Interface
For maximum flexibility, the ADS1115EVM is designed for easy interfacing to multiple analog sources.
Samtec part numbers SSW-110-22-F-D-VS-K and TSM-110-01-T-DV-P provide a convenient 10-pin,
dual-row, header/socket combination at J1. This header/socket provides access to the analog input pins of
the ADS1115. Consult Samtec at
or call 1-800-SAMTEC-9 for a variety of mating
connector options.
