Description
The CK5320 and CK5321 Chipsets function as a unique
A/D converter intended for very high resolution measure-
ment of signals below 1500 Hz. The CK5320 Chipset is
a cost effective commercial grade solution for applica-
tions which require a high dynamic range A/D converter.
The chipsets perform sampling, A/D conversion, and
anti-alias filtering.
The CS5320 and CS5321 use Delta-Sigma modulation
to produce highly accurate conversions. The
Σ
modula-
tor 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 periods: 16, 8, 4, 2, 1, 0.5
and 0.25 milliseconds. Data is output from the digital fil-
ter in a 24-bit serial format.
