The LTM2886CY-3S#PBF is a high-performance, isolated μModule (micro-module) transceiver from Linear Technology, which is now part of Analog Devices. This product is designed to provide robust isolation for SPI (Serial Peripheral Interface) communications, ensuring that data can be transferred safely even in environments with high levels of electrical noise or isolation requirements.

Key Features

• Isolation: The LTM2886CY-3S#PBF offers 2500V_RMS galvanic isolation, which separates the logic side from the bus side, protecting sensitive components and data integrity against high common mode voltages.
• SPI Interface: This transceiver supports SPI communication protocols, allowing for easy integration with a wide range of microcontrollers and digital systems.
• Integrated Power: It includes an isolated DC/DC converter that provides power to the isolated side, simplifying the design and reducing external component requirements.
• High Speed: Capable of high-speed operation, the LTM2886CY-3S#PBF can handle SPI clock speeds up to 20MHz, making it suitable for applications requiring fast data transfer rates.
• Robustness: The device is designed to operate reliably in harsh industrial environments, with features such as over-temperature protection and high ESD (Electrostatic Discharge) immunity.

Applications

The LTM2886CY-3S#PBF is ideal for a variety of applications where isolation is critical, such as:

• Industrial automation and process control
• Medical equipment with stringent safety requirements
• Automotive systems requiring isolation for safety and noise immunity
• Test and measurement equipment
