Description
The CS5451 is a highly integrated Delta-Sigma (
Σ)
An-
alog-to-Digital Converter (ADC) developed for the Power
Measurement Industry. The CS5451 combines six
Σ
ADCs, decimation filters, and a serial interface on a sin-
gle chip. The CS5451 interfaces directly to a current
transformer or shunt to measure current, and resistive
divider or transformer to measure voltage. The product
features a serial interface for communication with a mi-
cro-controller or DSP. The product is initialized and fully
functional upon reset, and includes a Voltage Reference.
