The CS5460A is a single-chip Delta-Sigma analog/digital converter (ADC) that integrates two Delta-Sigma ADCs, high-speed power calculation capabilities, and a serial interface. It is intended to precisely measure and compute energy, immediate power, IRMS, and VRMS for single-phase, two-wire, or three-wire power metering applications.
To measure current, the CS5460A attaches to a low-cost shunt resistor or transformer, and to a resistant divider or potential transformer to monitor voltage. It has a bidirectional serial interface for communicating with a microcontroller, as well as a configurable frequency output that is proportionate to energy. The CS5460A includes on-chip capabilities for AC or DC framework calibration.
The "Auto-Boot" functionality enables the CS5460A to operate independently and to initialise itself upon system power-up. The CS5460A reads dataset and begins giving??directives from an external EEPROM during Auto-Boot mode. In this mode, the CS5460A may operate without the need of a microprocessor, making it ideal for reduced cost??measuring purposes.
