CS5451A Description
The CS5451A is a highly integrated delta-sigma ( analog-to-digital converter (ADC) developed for the power measurement industry. The CS5451A bines six ADCs, 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.
