Controlling the ADS7805 With TMS320 Series DSPs
PDF, 69 Kb, File published: Nov 9, 2004
The ADS7805 16-bit, bipolar input, parallel output analog-to-digital converter (ADC) has features that allow for an easy interface to many of the TMS320 series of digital signal processors from Texas Instruments. This application report focuses on configuring, sampling, and converting analog data presented to the ADS7805 ADC, with software examples using the TMS320C6713 and TMS320C5416 DSPs. The

Tips for Using the ADS78xx Family of A/D Converters
PDF, 24 Kb, File published: Sep 27, 2000
The input to each of the members of the ADS Family (ADS7804/05/06/07/08/09/10/19, so far) is a resistor divider network, converting the input signal to the range used internally. This resistor divider offers inherent overvoltage protection, which will often simplify analog circuitry.
