Isolated Sigma Delta ADCs
As the world's leading supplier of data converters, Analog Devices are constantly introducing new ADCs that drive system architectures and deliver breakthrough combinations of performance and functionality. In the area of motor control, ADI’s converters solve the challenges associated with current and voltage monitoring, optical encoder feedback, and resolver-to-digital conversion. Specifically the introduction of the Isolated A/D Converter with its 3.75kV stand-off voltage is one example of the performance breathroughs and integration to ease the burden of design.
AD7403- 16-Bit, Isolated Sigma-Delta Modulator
The AD7403 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 AD7403 operates from a 5 V (VDD1) power supply and accepts a differential input signal of ±250 mV (±320 mV full-scale). The differential input is
