Analog Devices Isolation - All

AD7402 Isolated Sigma-Delta Modulators

Analog Devices AD7402 features high-performance, second-order, Σ-Δ modulators that convert 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 AD7402 operates from a 4.5 to 5.5V (V_DD1) 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. AD7402 continuously samples analog input using a high-performance analog modulator and converts it into a density, digital output stream with a data rate of 10MHz. Designers can reconstruct the original information with an appropriate digital filter to achieve an 87dB signal-to-noise ratio (SNR) at 39kSPS. The serial input/output can use a 3V to 5.5V or a 3.3V supply (V_DD2). Designed with high-speed CMOS technology and a digitally isolated serial interface, AD7402 is well-suited for shunt current monitoring, AC motor controls, power and solar inverters, wind turbine inverters, data acquisition systems, and analog-to-digital and optoisolator replacements.
