Description

This application report presents a hardware and software solution for interfacing the TLV2544/TLV2548 12-bit, 200-ksps, 4/8-channel, low-power, serial, successive approximation register (SAR) analog-to-digital converters (ADCs) to the 32-bit floating point TMS320C3X digital signal processor (DSP) through the use of the TMS320C31 DSP starter kit (DSK).

A digital-to-analog converter (DAC) interface to the DSP is also presented here exclusively for the single-shot mode operation of the ADC, since the DAC is used to reconstruct the digital data from the ADC for verification purposes. The TLV5618A DAC is used for this report.
