ADE7858AACPZ - Polyphase Multifunction Energy Metering IC

Product Description

ADE7858AACPZ is high accuracy, 3-phase electrical energy measurement ICs with serial interfaces and three flexible pulse outputs. The devices incorporate second-order Σ-Δ analog-to-digital converters (ADCs), a digital integrator, reference circuitry, and all signal processing required to perform total (fundamental and harmonic) active, reactive and apparent energy measurement and rms calculations.

Product Features

Supports current transformer and di/dt current sensors

Dedicated ADC channel for neutral current input

Estimated neutral current measurement by calculating the rms of the sum of the phase currents in all 3 phases

0.1% error (typical) in voltage and current rms over a dynamic range of 1000 to 1 at TA = 25°C

Supplies sampled waveform data on all 3 phases and on neutral current

Reference: 1.2 V (drift of ±5 ppm/°C typical) with external overdrive capability

Single 3.3 V supply

Operating temperature: −40°C to +85°C

Flexible I2C, SPI, and HSDC serial interfaces

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
