ADUM4152BRIZ

ADUM4152BRIZ Description

The ADUM4152BRIZ from Analog Devices Inc. is a high-performance 7-channel digital isolator designed for SPI (Serial Peripheral Interface) isolation applications. Utilizing magnetic coupling (iCoupler® technology), it provides robust 5000Vrms isolation with a data rate of 34Mbps, making it ideal for high-speed communication in noisy environments. The device operates over a 3V to 5.5V supply range and features unidirectional channels (4 inputs on Side 1 and 3 outputs on Side 2). Its low propagation delay (14ns max) and minimal pulse width distortion (2ns max) ensure signal integrity, while 25kV/µs common-mode transient immunity (CMTI) enhances reliability in industrial settings. Packaged in a 20-SOIC tube, it is RoHS3 compliant and rated for MSL 3 (168 hours).
