This file introduces the cirrus logic company's CS5460A power measurement chip, which has high precision, low power consumption and can be used for single phase 2- or 3-wire power measurement applications
The CS5460A is a highly integrated single‑phase, bi‑directional power and energy measurement IC designed for accurate real‑time energy, power, voltage and current monitoring. It includes on‑chip functions such as auto‑boot, calibration, and a serial interface for stand‑alone operation.
The document contains detailed analog and digital characteristics, pin descriptions, package dimensions, ordering information, calibration procedures, and a full register map. It also provides application notes, wiring diagrams, and mechanical interface options for various power‑metering configurations.
| Supply Voltage (VA+) | +5 V |
|---|---|
| Power Consumption (Active State) | 21–25 mW |
| Operating Temperature Range | -40 °C to +85 °C |
VA+ should be +5 V (or +3.3 V for low‑power operation).
