The ADuM7704 is a high performance, second-order, Σ-Δ 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 device operates from a 4.5 V to 20 V power supply range (VDD1) and accepts a pseudo differential input signal of ±50 mV (±64 mV full-scale). The pseudo 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 a ones density digital output stream with a data rate of up to 21 MHz. The original information can be reconstructed with an appropriate sinc3 digital filter to achieve an 82 dB signal-to-noise ratio (SNR) at 78.1 kSPS with a 256 decimation rate and a 20 MHz master clock. The serial input and output operates from a 5 V or a 3.3 V supply (VDD2).
