ADE7903- 3-Channel Sigma-Delta ADC with SPI
The ADE7903 is a nonisolated, 3-channel, Σ-Δ analog-to-digital converter (ADC) for the neutral line of polyphase energy metering applications using shunt current sensors. The ADE7903 can also be used for single-phase energy metering and other standalone ADC applications. The ADE7903 features three 24-bit ADCs. The current ADC provides a 67 dBFS signal-to-noise ratio (SNR) over a 3.3 kHz signal 続きを見るデータシート Rev 0, 12/2014 (pdf 939kB)
ADE7923- 3-Channel, Sigma Delta ADC
The ADE7978, the ADE7933/ADE7932, and ADE7923 form a chipset dedicated to measuring 3-phase electrical energy using shunts as current sensors.
The ADE7933/ADE7932 are isolated, 3-channel sigma-delta analog-to-digital converters (Σ-Δ ADCs) for polyphase energy metering applications that use shunt current sensors. The ADE7923 is a nonisolated, 3-channel Σ-Δ ADC for the neutral line that uses 続きを見るデータシート Rev A, 12/2014 (pdf 2421kB)
