ADE7913ARIZ-RL

The ADE7913ARIZ-RL is an integrated circuit designed and manufactured by Analog Devices, Inc. It is part of the company’s special purpose line of data acquisition products. The device’s application field is the transactional energy metering industry and its working principle is based on integration, filtration and non-linearity.

The chip offers a range of features for accurately monitoring power consumption in residential, commercial and industrial settings. Its advanced integration process and digital filtration capabilities make it particularly suitable for use in distributed energy networks, where accurate data capture from multiple sources is key to efficient energy management.

The ADE7913ARIZ-RL integrates a low-power, low-speed voltage converter with an integrated current transducer. The voltage converter captures the incoming power line signal and converts it to a digital 12-bit word. This word is then sent to an internal 16-bit accumulator where it is accumulated with other signals received. The accumulator then updates its contents every 8.192 msec, providing an output signal which is used to develop the current calculations.

The chip also contains an integrated, non-linearity compensation circuit which compensates for the effects of non-linearity inherent in power supplies. This circuit reduces the effect of large-scale changes in the power supply on the accuracy of the current measurement provided by the chip.

The ADE7913ARIZ-RL also includes an internal temperature sensor which can be used to measure the local temperature. This is useful for determining the amount of power being consumed at different temperatures, as well as for monitoring the temperature of the power line itself.

The chip also offers an integrated on-board power supply regulation circuit which is suitable for use with a variety of power supply types. This regulation circuit is designed to work with AC or DC supplies, tolerant to voltages between 4V and 20V. This wide range of operating parameters makes it suitable for a range of various input signal types and levels.

The ADE7913ARIZ-RL is designed to sample, convert and accumulate input signals into accurate data which can be used to accurately measure energy consumption in a wide variety of environments. Its integrated filtration and non-linearity compensation circuits, combined with its onboard power supply regulation, allow it to operate reliably in a variety of application conditions.
