## Description

Bidirectional power measurement module with Delta Sigma ADC, ideal for AC energy monitoring, calculates active and instantaneous power, IRMS and VRMS, offers high accuracy of +/-0.1%, operates at 3-5V and communicates serially over 3 wires with Arduino and other boards. Supports auto-boot with external EEPROM for autonomous operation at startup.
CS5460A multifunctional 3-5V bi-directional analog-digital converter, compatible with Arduino and other development boards.
The CS5460A module is a high-speed Delta-Sigma bidirectional analog-to-digital converter (ADC) and a high-precision serial interface adapter. (+/- 0.1%).
It can be used in applications for measuring and calculating active energy, instantaneous power, IRMS and VRMS, for alternating current installations. The current is measured using a transformer or a transformer. The voltage is measured with a voltage divider resistor or a voltage transformer.
In auto-start mode, the CS5460A reads the calibration profile from an external EEPROM according to the start-up instruction.
The "Auto-Boot" feature allows the module to run independently and initialize itself at system startup. In this mode, the CS5460A can operate without the need for a microprocessor (for low-cost measurement applications).
