EVAL-ADE7913 no-OS Project

The EVAL-ADE7913 provides a complete evaluation platform for the ADE7913 isolated sigma-delta ADC, enabling the prototyping, testing, and assessment of high-performance energy metering systems in realistic three-phase meter scenarios. The platform integrates hardware-specific configurations and interfaces—including SPI, UART, GPIO, and NVIC interrupt management—with robust application logic to demonstrate features such as dynamic RMS computation, burst mode read operations, and synchronized multi-device operations.

Applications

Shunt-based polyphase meters
Power quality monitoring

Pin Description

Phase Voltage Sense Inputs

Pin Number	Pin Name	Pin Function	Description
TP14/TP11	V1PIN Phase A	Phase Voltage Sense	Connect the phase voltage between TP14 and TP11. The attenuated signal is achieved using a resistor divider network with an RC antialiasing filter.
TP9/TP6	V1PIN Phase B	Phase Voltage Sense	Connect the phase voltage between TP9 and TP6.
TP4/TP1	V1PIN Phase C	Phase Voltage Sense	Connect the phase voltage between TP4 and TP1.

Auxiliary Voltage Sense Inputs

Pin Number	Pin Name	Pin Function	Description
TP15/TP11	V2PIN Phase A	Auxiliary Voltage Sense	Connect the auxiliary voltage between TP15 and TP11. This path uses a resistor divider network and filtering similar to the phase voltage inputs.
TP10/TP6	V2PIN Phase B	Auxiliary Voltage Sense	Connect the auxiliary voltage between TP10 and TP6.
TP5/TP1	V2PIN Phase C	Auxiliary Voltage Sense	Connect the auxiliary voltage between TP5 and TP1.
