The ADG201A is a monolithic CMOS device comprising four independently selectable switches. They are designed on an enhanced LC2MOS process which gives an increased signal handling capability of ±15 V. These switches also feature high switching speeds and low RONThe ADG201A switches are turned on with a logic low on the appropriate control input. Each switch conducts equally well in both directions when ON and each has an input signal range that extends to the supplies. All switches exhibit break-before-make switching action for use in multiplexer applications. Inherent in the design is low charge injection for minimum transients when switching the digital inputs.

The ADuM1250/ADuM1251 are hot swappable digital isolators with non-latching, bidirectional communication channels that are compatible with I2C interfaces. This eliminates the need for splitting I2C signals into separate transmit and receive signals for use with standalone optocouplers.The ADuM1250 provides two bidirectional channels, supporting a complete isolated I2C interface. The ADuM1251 provides one bidirectional channel and one unidirectional channel for applications where a bidirectional clock is not required.Both the ADuM1250 and the ADuM1251 contain hot swap circuitry to prevent glitching data when an unpowered card is inserted onto an active bus.These isolators are based on the iCoupler® chip scale transformer technology from Analog Devices, Inc. iCoupler is a magnetic isolation technology with functional, performance, size, and power consumption advantages as compared to optocouplers. With the ADuM1250/ADuM1251, iCoupler channels can be integrated with semiconductor circuitry, which enables a complete isolated I2C interface to be implemented in a small form factor.Applications Isolated I2C, SMBus, or PMBus interfaces Multilevel I2C interfaces Power supplies Networking Power over Ethernet Hybrid electric vehicle battery management

The ADuM1410 / ADuM1411 / ADuM1412 are four-channel digital isolators based on Analog Devices, Inc. iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices.By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The usual concerns that arise with optocouplers, such as uncertain current transfer ratios, nonlinear transfer functions, and temperature and lifetime effects, are eliminated with the simple iCoupler digital interfaces and stable performance characteristics. The need for external drivers and other discrete components is eliminated with these iCoupler products. Furthermore, iCoupler devices consume one-tenth to one-sixth the power of optocouplers at comparable signal data rates.The ADuM1410/ADuM1411/ADuM1412 isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide) up to 10 Mbps. All models operate with the supply voltage on either side ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products also have a default output control pin. This allows the user to define the logic state the outputs are to adopt in the absence of the input power. Unlike other optocoupler alternatives, the ADuM1410/ADuM1411/ ADuM1412 isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation
