The AD7401AYRWZ is an Isolated Sigma-Delta (Σ-Δ) Modulator that converts an analogue input signal to a high speed, 1-bit data stream with on-chip digital isolation based on iCoupler® technology. The AD7401A operates from a 5V power supply and accepts a differential input signal of ±250mV (±320mV full scale). The analogue input is continuously sampled by the analogue modulator, eliminating the need for external sample-and-hold circuitry. The input information is contained in the output stream as a density of ones with a data rate of 20MHz. The original information can be reconstructed with an appropriate digital filter. The serial I/O can use a 5V or a 3V supply (VDD2). 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. The part contains an on-chip reference.
