Analog Devices AD7865 Manuals

This application note describes how to interface parallel ADCs to ADSP-21365 SHARC® processors. The parallel ADC considered in this application note is the AD7865. The two schemes described in this application note to interface an AD7865 with an ADSP-21365 are the parallel port interface and the parallel data acquisition port (PDAP) interface. This application note also provides examples of how to use the PDAP interface to connect AD7865 to ADSP-21365.

This document explains how to interface parallel ADCs to ADSP-21161 SHARC® processors. The parallel ADC considered in this application note is AD7865. This application note also provides example code to demonstrate how the SHARC processor’s external port can be programmed to receive data from the AD7865 in core and DMA modes.

This document introduces the features and characteristics of AD7865 four-channel, simultaneous sampling, fast, 14-bit ADC.

The AD7865 is a fast, low power, four-channel simultaneous sampling 14-bit A/D converter that operates from a single 5V supply. The part contains a 2.4µs successive approximation ADC, four track/hold amplifiers, 2.5V reference, on-chip clock oscillator, sign...
