ADE7753ARSZ

Overview

The ADE7753ARSZ is a single-phase energy metering integrated circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.75 V to 5.25 V and features a 16-bit resolution with two sigma-delta ADCs. The device utilizes an SSOP-20 package and supports SPI communication. It functions across a temperature range of -40°C to +85°C with a typical power consumption of 25 mW.

Feature Summary

• Integrates a digital integrator for direct connection to di/dt current sensors such as Rogowski coils, eliminating the need for external analog integration components.
• Provides comprehensive signal processing for active, reactive, and apparent energy measurements alongside RMS and peak-to-peak calculations.
• Includes internal digital calibration capabilities for power, phase, and input offset adjustments to maintain measurement accuracy.

Applications

• Single-phase electricity metering systems
• Energy monitoring devices requiring high dynamic range accuracy
• Smart grid infrastructure components

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure the SSOP-20 package matches your PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component for single-phase applications requiring precise energy measurement without external integrators. Consider the pin-compatible ADE7756 and ADE7759 if different interface or channel configurations are needed. For three-phase designs, evaluate the ADE7758 instead.

Part Context

This part belongs to the ADE7753 series of specialized data acquisition ADCs designed for energy metering. It is distinct from polyphase variants like the ADE7751 and offers a dedicated solution for single-phase utility metering applications with integrated signal conditioning.

Replacement Considerations

Pin-compatible alternatives include the ADE7756 and ADE7759. Verify functional equivalence regarding interface protocols and sensor compatibility when substituting these parts in existing designs.

FAQ

Can the ADE7753 directly interface with Rogowski coils?

Yes, the built-in digital integrator allows direct connection to current sensors with di/dt outputs, such as Rogowski coils, removing the requirement for external analog integrators.

What types of current sensors can connect to the PGA?

The programmable gain amplifier (PGA) in the current channel can directly interface with low-impedance shunt resistors and current transformers.
