Description

The CS5321/CS5322 chipset functions as a unique

A/D converter intended for very high-resolution

measurement of signals below 1600 Hz. It is specif-

ically designed for applications that require both a

high dynamic range and a low total harmonic distor-

tion.

The

chipset

performs

sampling,

A/D

conversion, and anti-alias filtering.

The CS5321 uses Delta-Sigma modulation to pro-

duce

highly

accurate

conversions.

The

∆Σ

modulator oversamples, virtually eliminating the

need for external analog anti-alias filters. The

CS5322 linear-phase FIR digital filter decimates the

output to any one of seven selectable update peri-

ods: 16, 8, 4, 2, 1, 0.5, and 0.25 milliseconds. Data

is output from the digital filter in a 24-bit serial

format.
