CS5451A Datasheet (Cirrus Logic) - Delta-sigma Analog-to-digital Converter

CS5451A, Delta-sigma Analog-to-digital Converter

The CS5451A is a highly integrated delta-sigma ( analog-to-digital converter (ADC) developed for the power measurement industry.

The CS5451A combines six  ADCs, decimation filters, and a serial interface on a single chip.

The CS5451A interfaces directly to a current transformer or shunt to meas
