The ADUM1447ARQZ is a micropower, 4-channel digital isolator based on Analog Devices' iCoupler® technology. It combines high-speed CMOS and monolithic transformer technologies to provide superior performance compared to optocoupler devices.
This isolator supports up to a 2 Mbps data rate (NRZ) and offers high common-mode transient immunity of greater than 25 kV/µs. It operates with ultralow power consumption, featuring quiescent currents as low as 0.3 µA per channel when refresh is disabled at 3.3V operation, and 0.1 µA per channel at 2.5V operation.
The ADUM1447ARQZ is available in a compact 16-lead QSOP package, saving significant board space compared to wider SOIC packages. It is suitable for general-purpose, low-power multichannel isolation, 1 MHz low-power peripheral interface (SPI), and 4 mA to 20 mA loop process controls.
Key specifications include 2500Vrms isolation, a wide operating temperature range of -40°C to 125°C, and a data rate of 2Mbps. The device also features specific propagation delays and rise times, contributing to its high-speed performance.
