CS5532-BS Datasheet PDF - Cirrus Logic

General Description
The CS5532/34 are highly integrated ∆ΣAnalog-to-Digital Converters (ADCs) which use charge-balance techniques to achieve 24-bit performance. The ADCs are optimized for measuring low-level unipolar or bipolar signals in weigh scale, process control, scientific, and medical applications.
