ADS1256EVM and ADS1256EVM-PDK
This user's guide describes the characteristics, operation, and use of the ADS1256EVM, both by itself and
as part of the ADS1256EVM-PDK. This EVM is an evaluation fixture for the
(ΔΣ) analog-to-digital converter (ADC). It also serves as an evaluation platform for the ADS1255, which is
a proper subset of the ADS1256. It allows evaluation of all aspects of the ADS1256 device. A complete
circuit description, schematic diagram, and bill of materials are included.

- Page 4 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 ADS1256EVM-PDK is controlled by a plug-in that runs in ADCPro. For more information about ADCPro, see the ADCPro™...
- Page 5 It can be connected to any Modular EVM System interface card. The ADS1256EVM is available as a stand-alone printed circuit board (PCB) or as part of the ADS1256EVM-PDK, which includes an MMB0 motherboard and software. As a stand-alone PCB, the ADS1256EVM is useful for prototyping designs and firmware.
