Description

General part information

LTM2886 Series

The LTM2886 is a complete galvanic digital μModule®(micromodule) isolator. No external components are required. A single 3.3V or 5V supply powers both sides of the interface through an integrated, isolated DC/DC converter. A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Available options are compliant with SPI and I2C (master mode only) specifications.The isolated side includes fixed ±5V and 5V adjustable power supplies, each capable of providing more than 100mA of load current. The 5V adjustable supply may be programmed via an external voltage divider.Coupled inductors and an isolation power transformer provide 2500VRMSof isolation between the input and output logic interface. This device is ideal for systems where the ground loop is broken, allowing for a large common mode voltage range. Communication is uninterrupted for common mode transients greater than 30kV/μs.APPLICATIONSIsolated SPI or I2C InterfacesIndustrial SystemsTest and Measurement EquipmentBreaking Ground Loops
