Analog Devices Inc. AD7403/-8 16-Bit Isolated Sigma-Delta Modulators are 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 AD7403/-8 operates from a 5V (VDD1) power supply and accepts a differential input signal of ±250mV (±320mV full-scale). 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 a ones density digital output stream with a data rate of up to 20MHz.
