The ADN4650/ADN4651/ADN46521 are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 600 Mbps with very low jitter.The devices integrate Analog Devices, Inc., iCoupler® technology, enhanced for high speed operation, to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This technology allows drop-in isolation of an LVDS signal chain.Multiple channel configurations are offered, and the LVDS receivers on the ADN4651/ADN4652 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated, but not driven.For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply. An integrated on-chip low dropout regulator (LDO) can provide the required 2.5 V from an external 3.3 V power supply. The devices are fully specified over a wide industrial temperature range and are available in a 20-lead, wide body SOIC package with 5 kV rms isolation or a 20-lead SSOP package with 3.75 kV rms isolation.Applications Analog front-end (AFE) isolation Data plane isolation Isolated high speed clock and data links Isolated serial peripheral interface (SPI) over LVDS

The ADM2582E/ADM2587E are fully integrated signal and power isolated data transceivers with ±15 kV ESD protection and are suitable for high speed communication on multipoint transmission lines. The ADM2582E/ADM2587E include anintegrated isolated dc-to-dc power supply, which eliminates the need for an external dc-to-dc isolation block.They are designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E).The devices integrate Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator, a three-state differential line driver, a differential input receiver, and Analog Devices isoPower dc-to-dc converter into a single package. The devices are powered by a single 5 V or 3.3 V supply, realizing a fully integrated signal and power isolated RS-485 solution.The ADM2582E/ADM2587E driver has an active high enable. An active low receiver enable is also provided, which causes the receiver output to enter a high impedance state when disabled.The devices have current limiting and thermal shutdown features to protect against output short circuits and situations where bus contention may cause excessive power dissipation. The parts are fully specified over the industrial temperature range and are available in a highly integrated, 20-lead, wide-body SOIC package.The ADM2582E/ADM2587E contain isoPower technology that uses high frequency switching elements to transfer power throughthe transformer. Special care must be taken during printed circuit board (PCB) layout to meet emissions standards.

Gate Drivers Dual-Power MOSFET Driver

The AD7306 line driver/receiver is a 5 V monolithic product which provides an interface between TTL signal levels and dual standard EIA RS-232/RS-422 signal levels. The part contains two RS-232 drivers, one RS-422 driver, one RS-232 receiver, and one receiver path which can be configured either as RS-232 or as RS-422.An internal charge pump voltage converter facilitates operation from a single +5 V power supply. The internal charge pump generates ±10 V levels allowing RS-232 output levels to be developed without the need for external bipolar power supplies.A highly efficient charge pump design allows operation using non polarized, miniature 0.1 mF capacitors. This gives a considerable saving in printed circuit board space over conventional products which can use up to 10 mF capacitors. The charge pump output voltages may also be used to power external circuitry which requires dual supplies.The RS-232 channels are suitable for communications rates up to 100 kHz and the RS-422 channels are suitable for high speed communications up to 5 MHz. The RS-422 transmitter complementaryoutputs are closely matched and feature low timing skew between the complementary outputs. This is often an essential requirement to meet tight system timing specifications.All inputs feature ESD protection, all driver outputs feature high source and sink current capability and are internally protected against short circuits on the outputs. An epitaxial layer is used to guard against latch-up.The part is available in a 24-lead SOIC and 24-pin plastic DIP package.Applications DTE-DCE Interface Packet Switching Local Area Networks Data Concentration Data Multiplexers Integrated Services Digital Network (ISDN)

The AD8018 is a dual, high speed, low cost amplifier capable of driving low distortion signals to within 0.5 V of the supply rail. It is intended for use in single supply xDSL systems where low distortion and low cost is essential, and maximum reach on the line must be attained with the minimum of supply voltages. Each amplifier drives minimum 350 mA of output current and while maintaining -95 dBc of SFDR at 100 kHz, outstanding performance for any xDSL CPE application. The AD8018 is available with flexible standby and shutdown modes. Two bit control (1.5 V threshold referenced to DGND) will put the AD8018 into a full power standby (outputs low impedance) and shutdown (outputs high impedance).Fabricated in ADI's high speed XFCB process, the high bandwidth and fast slew rate of the AD8018 keep distortion to a minimum, while dissipating a minimum of power. The quiescent current of the AD8018 is low 9 mA/amplifier max. Low distortion, high output voltage drive, and high output current drive in small packages make the AD8018 ideal for use in low cost USB, PCMCIA and PCI Customer Premise Equipment for ADSL, SDSL, VDSL and proprietary xDSL systems.An evaluation board is available for this product and may be ordered using the following product number AD8018ARU-EVAL.
