The LTM2889 is a complete galvanically-isolated Controller Area Network (CAN) ?Module? (micromodule) transceiver. No external components are required ? a single supply powers both sides of the interface through an integrated, isolated DC/DC converter. Separate versions are available for 3.3V and 5V power supplies. The dual voltage CAN transceiver and the adjustable regulator allow 3.3V or 5V isolated power with either the 3.3V or 5V version.Coupled inductors and an isolation power transformer provide 2500VRMS of isolation between the line transceiver and the logic interface. This device is ideal for systems where the ground loop?is broken, allowing for large common mode voltage ranges. Communication remains uninterrupted for common mode transients greater than 30kV/?s.Supports up to 4Mbps CAN with Flexible Data Rate (CAN FD). A logic supply pin allows easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Enhanced ESD protection allows this part to withstand up to ?25kV Human Body Model (HBM) on the transceiver interface pins and ?10kV HBM across the isolation barrier without latchup or damage.Applications Isolated CAN Bus Interface Industrial Networks DeviceNet Applications

The fast 1Msps throughput with no cycle latency makes the LTC2378-20 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2378-20 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.The LTC2378-20 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier?s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 ? VREF and full-scale code from VREF to 0.9 ? VREF. For a typical reference voltage of 5V, the full-scale input range is now 0.5V to 4.5V, which provides adequate headroom for powering the driving amplifier from a single 5.5V supply.Applications Medical Imaging High Speed Data Acquisition Portable or Compact Instrumentation Industrial Process Control Low Power Battery-Operated Instrumentation ATE
