CDAC Architecture Gives ADC574 Pinout /Sampling, Low Power, New Input Ranges

 

This application note compares basic current-mode successive approximation A/Ds with CDAC-based architectures, and shows how adding a resistor divider network to the CDAC input permits the Burr-Brown ADS574 and ADS774 to fit existing ADC574 sockets. It then goes on to descibe some new analog input voltage ranges available on these parts due to the resistor network and CDAC approach.
