Description
The CK5320 and CK5321 Chipsets function as a unique A/D converter intended for very high resolution measurement of signals below 1500 Hz. The CK5320 Chipset is a cost effective commercial grade solution for applications which require a high dynamic range A/D converter. The chipsets perform sampling, A/D conversion, and anti-alias filtering.
