Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Shenzhen Mingjiada Electronics Co., LTD. (Recycling/Supply) (ADI) ADE9112ARNZ Dual channel isolated SIGma-δ analog-to-digital converter with SPI interface.

Overview:

ADE9112ARNZ is a precision synchronous sampling Σ-Δ analog-to-digital converter (ADC) for shand-based DC and polyphase energy metering applications. The ADE9112 features two fully differential sigma-δ ADC channels for isolated applications that require only a single voltage channel. The device contains a high-gain current channel that is best suited for use as a current sensor with shunt resistors. Multiple ADE9112 kits can be synchronized for simultaneous sampling and coherent output.

Applications

Multiphase meter based on shunt

Electric vehicle power supply equipment

Dc meter

Power quality monitoring

Solar inverter

Process monitoring

Protective equipment

Isolated sensor interface
