LTM2880EVPBF - Isolated μModule Transceiver from Linear Technology

The LTM2880EVPBF is a high-performance isolated μModule transceiver from Linear Technology, designed to provide robust communication in noisy environments. This innovative product offers a complete, galvanically isolated RS485/RS422 transceiver solution, integrating an isolated power supply, an isolated RS485/RS422 transceiver, and support components within a compact, enclosed package.

Key Features:

• Electrical Isolation: The LTM2880EVPBF provides up to 2500V RMS of isolation for one minute, ensuring signal integrity and protecting against high voltage spikes and ground loops.
• Integrated Power Supply: With an integrated, low-EMI, switch-mode power supply, the device simplifies design by providing power to the isolated side, eliminating the need for an external isolated DC/DC converter.
• Robust Communication: The transceiver supports RS485 and RS422 communication protocols, offering data rates up to 20Mbps. It is designed to handle the demanding requirements of extended communication distances and complex network topologies.
• Driver and Receiver Disable Functions: These allow the transceiver to enter a low-power shutdown mode, reducing power consumption when not in active use.
• High Common-Mode Transient Immunity: The LTM2880EVPBF is capable of withstanding common-mode transients of >30kV/μs, providing reliable data transmission even in electrically noisy environments.

Applications:

The LTM2880EVPBF is ideal for a wide range of applications where isolation is critical for system performance and reliability. It is commonly used in:

• Industrial field buses
• Networked control systems
• Instrumentation
• Medical equipment
• Data acquisition systems

Package and Quality:

The device is offered in a compact 15mm x 15mm x 4.92mm surface-mount LGA package, which is suitable for space-constrained applications. Additionally, the LTM2880EVPBF has been rigorously tested for quality and reliability, ensuring that it meets the stringent standards expected of Linear Technology products.

With its combination of isolation, integrated power supply, and robust communication capabilities, the LTM2880EVPBF is a versatile solution that addresses the challenges of complex electrical environments, providing designers with a reliable and easy-to-use transceiver option.
