CS5462 Datasheet PDF - Cirrus Logic

Description
The CS5462 is a low cost power meter solution combining two ∆Σ Analog-to-Digital Converters (ADC)’s, an energy-to-frequency converter, and energy pulse outputs on a single chip. It is designed to accurately measure and calculate energy for single phase 2- or 3-wire power metering applications with minimal external components.
