ADS1258EVM-PDK Evaluation Module
This user's guide describes the characteristics, operation, and use of the
This EVM is an evaluation platform for the ADS1258, a 24-bit, 125-kSPS, 16-channel (multiplexed), delta-sigma
(ΔΣ) analog-to-digital converter (ADC). The ADS1258 offers excellent noise performance, fast sampling speeds,
a programmable channel sequencer, and access to the multiplexer output for efficient signal conditioning. The
ADS1258EVM eases the evaluation of the device with hardware, software, and computer connectivity through
the universal serial bus (USB) interface. This user's guide includes complete circuit descriptions, schematic
diagrams, and a bill of materials. Throughout this document, the abbreviation EVM and the term evaluation
module are synonymous with the ADS1258EVM.
The ADS1258EVM and software can also support the 16-bit
must manually remove the ADS1258 and install the ADS1158. See
ADS1258 on the EVM. The ADS1158 is not discussed further in this document.
