ADI has excellent professional experience in integrated energy measurement, and there are 300 million electric meters using ADI metering technology; ADI‘s high-precision converters and operational amplifiers ensure precise measurement of voltage and current; digital-analog/analog About 50% of the power equipment of digital converters are converters using ADI; ADI‘s high-performance signal processing capability ensures real-time and reliable operation of the power grid; ADI provides system-level mixed-signal design solutions for power applications, simplifying the design complexity and shorten product design cycles; ADI helps users reduce system costs through innovation and increased signal processing integration. The following editor will introduce to you several ADI mixed signal processing chips.

1. ADE7953 is a single-phase multi-function meter integrated circuit with neutral current measurement, which measures the voltage and current of the live wire with high precision, and calculates the active, reactive and apparent power as well as the instant RMS voltage and current. The device includes three Delta-Sigma ADCs and high-precision energy measurement cores. The ADE7953 is suitable for single-phase metering applications around the world. Within a dynamic range of 3000:1, its active and reactive power calculation errors are less than 0.1%, and the accuracy is industry-leading Highest. For neutral current, its active and reactive power calculation error is less than 0.1% over a 1000:1 dynamic range. Using the zero-line current measurement function, the meter tampering detection and higher billing accuracy can be realized.

2. Three-phase multi-function energy metering IC ADE7880 with integrated harmonic monitoring is a high-precision, three-phase energy metering IC. It adopts serial interface and provides three flexible pulse outputs. The device houses multiple second-order sigma-delta analog-to-digital converters (ADCs), digital integrators, reference circuits, and all necessary signal processing circuits for total (fundamental and harmonic) active/apparent power measurements and RMS calculation, and fundamental active/reactive power measurement.

3. The ADE7169 integrates ADI‘s energy (ADE) metering IC analog front-end and fixed-function DSP solutions with an enhanced 8052 MCU core, RTC, LCD driver, and all peripherals to provide an energy meter with an LCD display. The ADE measurement core includes active, reactive and apparent power calculations as well as voltage and current rms measurements. This information can be used directly for billing purposes via the built-in energy scalar. The energy metering DSP includes many power line monitoring functions (such as SAG, peak and zero-crossing, etc.) to simplify meter design. The ADE7169 also includes a 108/104 segment LCD driver that generates voltages capable of driving the LCD up to 5 V.

4. ADuCRF101 is a fully integrated system-on-chip (SoC) solution designed for low-power wireless applications, with built-in 431-464 MHz and 862-928 MHz UHF transceivers, low-power ARM Cortex-M3 cores and Flash /EE memory, the device operates directly from a 3.6V battery and is designed for low-power operation, using an autonomous packet processor to minimize system power consumption during wireless communications.
