Multiplexing the CS556x/7x/8x Delta-Sigma ADCs
1. INTRODUCTION
The CS556x/7x/8x devices represent a new generation of delta-sigma analog-to-digital converters that pete with SAR (successive approximation register) converters, with some distinct advantages. The unique Features of these over-sampling converters allow them to be multiplexed at high speed across many input channels, because every conversion produces a fully settled result. In this application note the similarities and differences between SAR converters and the CS556x/7x/8x family of ADCs will be discussed as well as some design tips on choosing .. the right multiplexer and input amplifiers to drive...
