AD1555 - 24-Bit ADC WITH LOW NOISE PGA

Download the AD1555 datasheet PDF. This datasheet also covers the AD1 variant, as both devices belong to the same 24-bit adc with low noise pga family and are provided as variant models within a single manufacturer datasheet.

General 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.
