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 specifically designed for applications that require both a high dynamic range and a low total harmonic distortion. The chipset performs sampling, A/D conversion, and anti-alias filtering.
