Analog Devices ADuM144x Quad-Channel Digital Isolators are micropower devices based on iCoupler® technology. ADI ADuM144x isolators combine high speed, CMOS, and monolithic air core transformer technologies to provide outstanding performance characteristics compared to optocoupler devices.

The ENX signals can be used to disable the internal refresh, which lowers the total quiescent current to less than 1µA. These devices free almost 70% of board space but can still withstand high isolation voltages and meet regulatory requirements. ADuM144x isolators operate with supplies as low as 2.25V. This device family also provides low, pulse width distortion <8ns. These devices also have an input glitch filter to protect against extraneous noise disturbances.

Analog Devices AD5687/AD5687R Dual 12-Bit nanoDAC+™ are low power, dual, 12-bit, buffered voltage output digital-to-analog converters (DACs). The devices include a gain select pin giving a full-scale output of 2.5V (gain = 1) or 5V (gain = 2). The AD5687/AD5687R operate from a single 2.7V to 5.5V supply, are guaranteed monotonic by design, and exhibit less than 0.1% FSR gain error and 1.5mV offset error performance. Devices are available in a 3mm × 3mm LFCSP and a TSSOP package. The AD5687/AD8687R also incorporate a power-on reset circuit and a RSTSEL pin that ensure that the DAC outputs power up to zero scale or midscale and remain there until a valid write takes place. Each part contains a per channel power-down feature that reduces the current consumption of the device to 4μA at 3V while in power-down mode. The AD5687/AD5687R use a versatile serial peripheral interface that operates at clock rates up to 50MHz. Each device contains a VLOGIC pin that is intended for 1.8V/3V/5V logic.
Analog Devices ADM3485E Low Power Data Transceiver provides ±15kV ESD protection and is suitable for half-duplex communication on multipoint bus transmission lines. The ADM3485E is designed for balanced data transmission and complies with TIA/EIA standards RS-485 and RS-422. The ADM3485E is a half-duplex transceiver that shares differential lines and has separate enable inputs for the driver and the receiver. The devices have a 12kΩ receiver input impedance, which allows up to 32 transceivers on a bus. Because only one driver should be enabled at any time, the output of a disabled or powered-down driver is tristated to avoid overloading the bus. The receiver has a fail-safe feature that ensures a logic high output when the inputs are floating. Excessive power dissipation caused by bus contention or by output shorting is prevented with a thermal shutdown circuit.
Analog Devices ADL5511 RF RMS Detector is an RF envelope and TruPwr™ rms detector. The envelope output voltage is presented as a voltage that is proportional to the envelope of the input signal. The rms output voltage is independent of the peak-to-average ratio of the input signal. The rms output is a linear-in-V/V voltage with a conversion gain of 1.9V/Vrms at 900MHz. The envelope output has a conversion gain of 1.46V/V at 900MHz and is referenced to an internal 1.1V reference voltage, which is available on the EREF pin. The ADL5511 can operate from dc to 6GHz on signals with envelope bandwidths up to 130MHz. The extracted envelope can be used for RF power amplifier (PA) linearization and efficiency enhancements and the rms output can be used for rms power measurement. The high rms accuracy and fast envelope response are particularly useful for envelope detection and power measurement of broadband, high peak-to-average signals that are used in CDMA2000, W-CDMA, and LTE systems.

Analog Devices ADuM4160 USB Digital Isolator is a USB port isolator based on iCoupler® technology. ADI ADuM4160 combines high speed CMOS and monolithic air core transformer technology to provide outstanding performance characteristics. The device is easily integrated with low and full speed USB-compatible peripheral devices. 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. ADI 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. ADuM4160 provides isolated control of the pull-up resistor to allow the peripheral to control connection timing.
