CS5451A  
Six-Channel Delta-Sigma Analog-to-Digital Converter  
Features  
Description  
The CS5451A is a highly integrated Delta-Sigma (∆Σ)  
Analog-to-Digital Converter (ADC) developed for the  
Power Measurement Industry. The CS5451A combines  
six ∆Σ ADCs, decimation filters, and a serial interface on  
a single chip. The CS5451A interfaces directly to a cur-  
rent transformer or shunt to measure current, and  
resistive divider or transformer to measure voltage. The  
product features a serial interface for communication  
with a micro-controller or DSP. The product is initialized  
and fully functional upon reset, and includes a Voltage  
Reference.  
Synchronous Sampling  
On-chip 1. 2V Reference (25ppm/°C typ)  
Power Supply Configurations:  
– VA+ = +3 V; VA- = -2 V; VD+ = +3 V  
– Supply tolerances 10%  
Power Consumption  
– 20 mW Typical at VD+ = +3 V  
Simple Four-wire Serial Interface  
Charge Pump Driver output generates  
negative power supply.
