Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

ADE7903ARWZ is a non-isolated 3-channel sigm-δ analog-to-digital converter (ADC) that enables zero-line detection for three-phase power metering applications using shunt sensors. The ADE7903 can also be used for single-phase energy metering and other stand-alone ADC applications. ADE7903 integrates three 24-bit ADCs. Current ADCs can provide 67 dBFS signal-to-noise ratio (SNR) over 3.3 kHz signal bandwidth, while voltage ADCs can provide 72 dBFS signal-to-noise ratio over the same bandwidth.
