Description

This Electronic Component Model, AD7724ASTZ-REEL, is part of the ADCs/DACs product category. It consists of two seventh order sigma-delta modulators that convert analog input signals into high-speed 1-bit data streams. With a 5V power supply, it accepts a differential input range of 0V to +2.5V or ±1.25V centered around a common-mode bias. The analog inputs are continuously sampled by the analog modulators, eliminating the need for external sample-and-hold circuitry. The input information is encoded in the output stream as a density of ones and can be digitally reconstructed with an appropriate digital filter.
