The AD7402-8BRIZ is a 16-bit Isolated Sigma-Delta Modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc, iCoupler? technology. The differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required. The analog input is continuously sampled by a high performance analog modulator and converted to an ones density, digital output stream with a data rate of 10MHz. The original information can be reconstructed with an appropriate digital filter to achieve 87dB signal to noise ratio (SNR) at 39kSPS. The serial interface is digitally isolated. High speed complementary metal oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices.
