The ADuM3150?is a 6-channel SPIsolator? digital isolator optimized for isolated serial peripheral interfaces (SPIs). Basedon the Analog Devices, Inc., iCoupler? chip scale transformertechnology, the low propagation delay in the CLK, MO/SI,MI/SO, and SS SPI bus signals supports SPI clock rates of up to 17 MHz. These channels operate with 14 ns propagation delayand 1 ns jitter to optimize timing for SPI.The ADuM3150 isolator also provides two additional independentlow data rate isolation channels, one channel in each direction. Data in the slow channels is sampled and serialized for a 250 kbps data rate with 2.5 ?s of jitter.The ADuM3150 supports a delay clock output on the master side of the device. This output can be used with an additionalclocked port on the master to support 40 MHz clock performance. See the Delay Clock section for more information.Applications Industrial programmable logic controllers (PLC) Sensor isolation

The ADuM5210?/ADuM5211?/?ADuM5212 are dual-channel digitalisolators with isoPower?, an integrated, isolated dc-to-dc converter. Based on the Analog Devices, Inc., iCoupler? technology, the dc-to-dc converter provides regulated, isolated power that is adjustablebetween 3.135 V and 5.25 V. Input supply voltages can range from slightly below the required output to significantly higher. Popularvoltage combinations and their associated power levels are shown in Table 2 in the data sheet.The ADuM5210 / ADuM5211 / ADuM5212 eliminate the need for aseparate, isolated dc-to-dc converter in low power, isolated designs.The iCoupler chip-scale transformer technology is used for isolatedlogic signals and for the magnetic components of the dc-to-dcconverter. The result is a small form factor, total isolationsolution.isoPower uses high frequency switching elements to transfer power through its transformer. Take special care during printed circuit board (PCB) layout to meet emissions standards.

DC1079A-B: Demo Board for the LTC4310 Hot-Swappable I2C Isolators.

The LTM2810 is a complete galvanic digital ?Module? (micromodule) isolator. No external components are required. Individual 3V to 5.5V supplies power each side of the digital isolator. Separate logic supply pins allow easy interfacing with different logic levels from 1.62V to 5.5V, independent of the main supply.Module options are available with compatibility to SPI (LTM2810-S) and I2C (LTM2810-I), master mode only, specifications.The module includes an integrated transformer driver on the logic side and an LDO on the isolated side to regulate the rectified transformer output. The LDO output is nominally 5V but may be overdriven.Coupled inductors provide 7500VRMS of isolation between the input and output logic interface. This device is ideal for systems with different ground potentials, allowing uninterrupted communication through large common mode transients faster than 50kV/?s.APPLICATIONS EV/HEV Systems Industrial and Metering Systems Test and Measurement Equipment Medical Equipment

The ADM2561E, ADM2563E, ADM2565E, and ADM2567E are 3 kV rms signal and power isolated RS-485 transceivers. These devices are designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The devices pass radiated emissions testing to the EN 55032 Class B standard with margin on a 2-layer printed circuit board (PCB) using two small external 0402 ferrites on isolated power and ground pins. The device features an integrated, low electro-magnetic interference (EMI), isolated dc-to-dc converter, which eliminates the need for an external isolated power supply. The isolation barrier provides immunity to system level electromagnetic compatibility (EMC) standards. The family of isolator devices features ?12 kV contact and ?15 kV air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Z pins. The devices also features cable invert pins, allowing the user to quickly correct reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance.Slew rate limited versions are available, which are optimized for low speed over long cable runs, and have a maximum data rate of 500 kbps. Half duplex and full duplex variants are available. The full duplex generics allow independent cable inversion of the driver and receiver for additional flexibility.Applications Heating, ventilation, and air-conditioning (HVAC) networks Industrial field buses Building automation Utility networks Energy meters
