Description

The CS5451A is a highly integrated, Delta-Sigma analog-to-digital (A/D) converter developed for the power measurement industry. The CS5451A combines six Delta-Sigma A/D converters, decimation filters and a serial interface on a single chip.

The CS5451A interfaces directly to a current transformer or shunt to measure current and to a resistive 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.
