AD7400AYRWZ

AD7400A is a second-order, Σ-Δ modulator that converts an analogue input signal into a high speed, 1-bit data stream with on-chip digital isolation based on Analog Devices, Inc., iCoupler® technology. The serial interface is digitally isolated. High speed CMOS, combined with monolithic air core transformer technology, means the on-chip isolation provides outstanding performance characteristics superior to alternatives such as optocoupler devices. Typical application includes AC motor controls, shunt current monitoring, data acquisition systems and analogue-to-digital and opto-isolator replacements.
