ADS126xEVM Overview
The ADS126xEVM-PDK is an evaluation module using the MMB0 hardware and ADCPro software
platform for evaluation of the ADS1262 and ADS1263 (both referenced to as ADS126x in this document).
The standalone ADS126xEVM is useful for prototyping designs and firmware.
1.1
EVM Features
•
Includes all required support circuitry for the ADS1262 and ADS1263
•
ADCPro
evaluation software for Windows XP™ and Windows 7™ operating systems, with built-in
analysis tools
•
Configurable inputs, references, supplies, and clock sources
•
Easily accessible signals through test points and headers
1.2
Hardware Overview
The EVM layout is partitioned as follows: the analog input/output (I/O) section, digital I/O header, power
components, and clock circuitry. All these sections connect to the ADS126x TSSOP package located in
the center of the EVM.
Figure 2
shows the EVM connected to the MMB0 motherboard.
The MMB0 provides two main functions:
1. Provides power to the ADS126xEVM
2. Interfaces between ADCPro and the ADS126x.
The default configuration of the MMB0 is sufficient to configure the ADS126x with a single supply. See
Section 2.3.2
to configure the EVM with bipolar supplies. A schematic of the MMB0 motherboard is
available at ftp://ftp.ti.com/pub/data_acquisition/ADCPro/Support/MMB0_Sch_RevD.PDF. The MMB0 is
intended to be used with the accompanying EVM software and does not have additional resources to
support the use as a firmware development platform.
