CS5534-BS
数据手册.pdfQuad Channel Single ADC Delta-Sigma 3.84KSPS 24Bit Serial Automotive 24Pin SSOP
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.
