Evaluation Board for Analogue Isolator using AD7400A

An Analogue Devices evaluation board demonstrating a novel analogue-to-analogue isolator using an isolated Sigma-Delta Modulator, isolated DC-DC Converter and active filter.
The circuit is based on the AD7400A, a second-order, sigma-delta modulator with a digitally isolated 1-bit data stream output. The isolated analogue signal is recovered with a fourth-order active filter based on the dual, low noise, rail-to-rail AD8646 op amp. With the ADuM5000 as the power supply for the isolated side, the two sides are completely isolated and use only one power supply for the system. The circuit has 0.05% linearity and benefits from the noise shaping provided by the modulator of the AD7400A and the analogue filter. Typical applications include motor control and shunt current monitoring, and the circuit is also an excellent alternative to opto-based isolation systems.

The evaluation board includes the following ICs:

AD7400A Isolated Sigma-Delta Modulator
ADuM5000 Isolated DC-to-DC Converter
AD8646 Dual 24 MHz Rail-to-Rail I/O Op-Amp
ADP121 150mA CMOS Linear Regulator
ADP3301 High Accuracy 100 mA LDO Linear Regulator
ADG849 3V/5V CMOS 0.5Ω SPDT/2:1 MUX
ADR443 Ultra-low-noise LDO XFET 3.0V Reference
