1. INTRODUCTION

The CS556x/7x/8x devices represent a new generation of delta-sigma analog-to-digital converters that compete

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 these ADCs.
