CS5531-AS Datasheet - Cirrus Logic

CS5531-AS 16-bit and 24-bit ADC

The CS5531/32/33/34 are highly integrated  Analogto-Digital Converters (ADCs) which use charge-balance techniques to achieve 16-bit (CS5531/33) and 24-bit (CS5532/34) performance. The ADCs are optimized for measuring low-level unipolar or bipolar signals in weigh scale, process control, scientific.
