Description
The CS5466 is a low-cost power meter solution incorporating dual delta-sigma (∆Σ) analog-to-digital converters (ADCs), an energy-to-frequency converter, and energy pulse outputs on a single chip. The CS5466 is designed to accurately measure and calculate energy for single phase, 2- or 3-wire power metering applications with minimal external components.
