The ADuM3470 / ADuM3471 / ADuM3472 / ADuM3473 / ADuM3474 devicesare quad-channel, digital isolators withan integrated PWM controller and transformer driver for an isolated DC/DC converter. Based on the Analog Devices, Inc., iCoupler® technology, the DC/DC converter provides up to 2 W of regulated, isolated power at 3.3 V to 24 V from a 5.0 V input supply or from a 3.3 V supply. This eliminates the need for a separate, isolated DC/DC converter in 2 W isolated designs. The iCoupler chip-scale transformer technology is used to isolate the logic signals, and the integrated transformer driver withisolated secondary side control provides higher efficiency for the isolated DC/DC converter. The result is a small form factor, total isolation solution.The ADuM347x isolators provide four independent isolationchannels in a variety of channel configurations and data rates.APPLICATIONS RS-232/RS-422/RS-485 transceivers Industrial field bus isolation Power supply startup bias and gate drives Isolated sensor interfaces Process controls Automotive

The ADuM4160 is a USB port isolator, based on Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics and are easily integrated with low and full speed USB-compatible peripheral devices.Many microcontrollers implement USB so that it presents only the D+ and D− lines to external pins. This is desirable in many cases because it minimizes external components and simplifies the design; however, this presents particular challenges when isolation is required. USB lines must automatically switch between actively driving D+/D−, receiving data, and allowing external resistors to set the idle state of the bus. The ADuM4160 provides mechanisms for detecting the direction of data flow and control over the state of the output buffers. Data direction is determined on a packet-by-packet basis.The ADuM4160 uses the edge detection based iCoupler technology in conjunction with internal logic to implement a transparent, easily configured, upstream facing port isolator. Isolating an upstream facing port provides several advantages in simplicity, power management, and robust operation.The isolator has propagation delay comparable to that of a standard hub and cable. It operates with the supply voltage on either side ranging from 3.1 V to 5.5 V, allowing connection directly to VBUS by internally regulating the voltage to the signaling level. The ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing. The device has a low idle current; a suspend mode is not required.APPLICATIONS USB peripheral isolation Isolated USB hub Medical applications

The ADuM440x are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics that are superior to the alternatives, such as optocoupler devices and other integrated couplers.The ADuM440x isolators provide four independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide). All models operate with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling a voltage translation functionality across the isolation barrier. The ADuM440x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and during power-up/power-down conditions.This family of isolators, like many Analog Devices isolators, offers very low power consumption, consuming one-tenth to one-sixth the power of comparable isolators at comparable data rates up to 10 Mbps. All models of the ADuM440x provide low pulse width distortion (<2 ns for C grade). In addition, every model has an input glitch filter to protect against extraneous noise disturbances.The ADuM440x contain circuit and layout enhancements to help achieve system-level IEC 61000-4-x compliance (ESD/burst/surge). The precise capability in these tests for the ADuM440x are strongly determined by the design and layout of the user’s board or module.
