Description

The CS5451A is a highly integrated delta-sigma (

ΔΣ) an-

alog-to-digital converter (ADC) developed for the power

measurement industry. The CS5451A combines six

ΔΣ

ADCs, decimation filters, and a serial interface on a sin-

gle chip. The CS5451A interfaces directly to a current

transformer or shunt to measure current, and to a resis-

tive divider or transformer to measure voltage. The

product features a serial interface for communication

with a microcontroller or DSP. The product is initialized

and fully functional upon reset, and includes a voltage

reference.
