LTM2810CY-S#PBF

Overview

The LTM2810CY-S#PBF is a μModule isolator from Analog Devices Inc. designed for SPI, digital, or I2C interfaces. It integrates a transformer driver and provides 7.5kVRMS isolation. The device features six channels with a propagation delay of 300 ns and a common-mode transient immunity (CMTI) of 50kV/µs. Operating supply voltage ranges from 1.62 V to 5.5 V, with an operating supply current of 3.6 mA. It functions within a temperature range of 0°C to 70°C and utilizes a 36-lead BGA package.

Feature Summary

• Integrates a transformer driver for isolated communication
• Provides high common-mode transient immunity
• Supports multiple interface protocols including SPI and I2C

Applications

• Industrial process control systems requiring galvanic isolation
• Medical equipment needing signal isolation between circuits
• Automotive electronics utilizing isolated data buses

Procurement Notes

Verify the specific suffix 'S' indicates the commercial temperature grade (0°C to 70°C). Confirm the package type matches the 36-lead BGA specification. Ensure the order includes the correct tape and reel quantity if required for automated assembly. Check for RoHS compliance documentation as per manufacturer standards.

Selection Notes

Select this component when high CMTI is critical for noise immunity in harsh environments. Compare against standard optocouplers for size and speed advantages. Consider the integrated transformer driver to reduce external component count. Evaluate power consumption requirements against the 3.6 mA supply current specification.

Part Context

This part belongs to the LTM2810 family of μModule isolators. It differs from variants like LTM2810CY-I#PBF primarily by its operating temperature range. The series is designed to replace discrete isolation solutions in compact designs.

Replacement Considerations

LTM2810CY-SPBF is listed as a related variant. Verify pinout compatibility before substitution. Ensure thermal performance meets system requirements for the specific grade.
