Product details

The AD7755AAN is a single-phase energy metering IC from Analog Devices. It outputs a frequency proportional to the real power, directly driving a stepper motor or microcontroller counter. The 0.1% measurement error meets utility-grade metering requirements. The 390 kΩ input impedance sets the voltage divider ratio for the mains sensing network. The 2 mA supply current allows a simple capacitive dropper or small transformer for the power supply.

It is not RoHS compliant, so designs requiring lead-free assembly should consider the AD7755AARSRL surface-mount variant or verify exemption applicability.

Frequently asked questions

What is the equivalent part for AD7755AAN?

The closest functional equivalent within the same series is the AD7755AN, which shares the same 0.1% measurement error, 390 kΩ input impedance, and 24-DIP package. The AD7751AAN is another single-phase metering IC with a slightly different input impedance (400 kΩ) and the same package and error spec. Neither is a direct drop-in without reviewing the datasheet for output scaling differences.

What is AD7755AAN's meter type?

The AD7755AAN is a single-phase energy metering IC, designed for residential and light commercial electricity meters.
