The ADS131A04EVM is an evaluation module kit that provides hardware and software support for
evaluation of the ADS131A04 delta-sigma analog-to-digital converter (ADC). The kit utilizes the
TM4C1294NCPDT processor to communicate with the ADC via SPI and provide communication with a PC
over USB interface. The kit also includes a software application that runs on a PC allowing for register
manipulation and data collection from the ADC.
!
Do not connect inputs of this EVM to voltages higher than 5 VAC to
minimize shock hazard.

Access the digital signals of the device via J3. This header allows for the connection to a logic analyzer or when the EVM is used in a stand-alone configuration for connections to the microprocessor or microcontroller. If controlling the ADS131A04 with an external processor is desired, power down the onboard TM4C1294NCPDT by placing a jumper on JP1. Clock By default, a clock is supplied to the ADC via an external 16.384-MHz crystal. -
