ATM90E36A-AU is a poly-phase high performance wide-dynamic range metering IC. ATM90E36A-AU incorporates 7 independent 2nd order sigma delta ADCs, which could be employed in three voltage channels and four current channels in a typical three-phase four-wire system.

Features

3.3V single power supply. Operating voltage range: 2.8V~3.6V. Metering accuracy guaranteed within 3.0V~3.6V.

Four-wire SPI interface with Direct Memory Access (DMA) mode to stream out 7-channel ADC raw data.

Parameter diagnosis function and programmable interrupt output of the IRQ inter rupt signals and the WarnOut signal.

Programmable voltage sag detection and zero-crossing output.

CF1/CF2/CF3/CF4 output active/ reactive/ apparent energy pulses and fundamental/ harmonic energy pulses respectively.

Crystal oscillator frequency: 16.384 MHz. On-chip two capacitors and no need of external capacitors.

Operating temperature: -40 ℃ ~ +85 ℃ .

Applications

Poly-phase energy meters of class 0.2S, 0.5S and class 1 which are used in three-phase four-wire (3P4W, Y0) or three-phase three-wire (3P3W, Y or Δ) systems.

Data Acquisition Terminal.

Power monitoring instruments which need to measure voltage, current, THD,DFT, mean power, etc.

• 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?
