The ADUM4151ARIZ is a 5 kV rms, 7-channel SPIisolator™ digital isolator optimised for isolated serial peripheral interface (SPI) applications. The ADUM4151ARIZ device is based on ADI's iCoupler® chip-scale transformer technology, offering low propagation delay characteristics in CLK, MO/SI, MI/SO, and SS SPI bus signals, supporting SPI clock rates up to 17 MHz. These channels have a propagation delay of 14 ns and jitter of 1 ns during operation, optimised for SPI timing.
ADUM4151ARIZ Product Features
High isolation voltage: Supports isolation voltages up to 2.5 kV rms, effectively isolating electrical signals between the input and output ends to ensure the safety and reliability of data transmission.
High-speed transmission: Channel bandwidth up to 25 Mbps, meeting the requirements for high-speed digital signal transmission, suitable for applications with high real-time performance demands.
Low power consumption: Typical static current as low as 0.97 mA per channel, helping to reduce system power consumption and suitable for battery-powered portable devices.
High common-mode transient immunity (CMTI): Reaches 50 kV/μs, ensuring stable operation in complex electromagnetic environments and preventing common-mode noise interference.
Wide operating voltage range: Operating voltage ranges from 2.8 V to 5.5 V, suitable for various power supply environments.
Multiple channel configurations: Provides one forward channel and one reverse channel, meeting the needs of different signal flow directions.
Multiple reset modes: Supports multiple reset modes, including open-drain output, push-pull output, and I2C reset, allowing users to select the appropriate mode based on application requirements.
Compact packaging: Uses an 8-pin SOIC package with dimensions of 4.90 × 3.91 mm and a height of 1.75 mm, saving printed circuit board space.
