AD1555 - 24-Bit ADC WITH LOW NOISE PGA

This page provides the datasheet information for the AD1555, a member of the AD1 24-Bit ADC WITH LOW NOISE PGA family.

Datasheet Summary

Description

high dynamic range measurement applications.

The AD1555 outputs a ones-density bitstream proportional to the analog input.

When used in conjunction with the AD1556 digital filter/ decimator, a high performance ADC is realized.
