The ADuM130x are triple-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives, such as optocouplers.By avoiding the use of LEDs and photodiodes, iCoupler devices remove the design difficulties commonly associated with optocouplers. The typical optocoupler concerns regarding 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 of the power of optocouplers at comparable signal data rates.The ADuM130x isolators provide three independent isolation channels in a variety of channel configurations and data rates (see the Ordering Guide in the data sheet). Both 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 a voltage translation functionality across the isolation barrier. In addition, the ADuM130x provide low pulse width distortion (<2 ns for CRW grade) and tight channel-to-channel matching (<2 ns for CRW grade). Unlike other optocoupler alternatives, the ADuM130x isolators have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation RS-232/RS-422/RS-485 transceivers Industrial field bus isolation Automotive systems

The ADP1870 / ADP1871?are versatile current-mode, synchronous step-down controllers that provide superior transient response, optimal stability, and current-limit protection by using a constant on-time, pseudo-fixed frequency with a programmable current limit, current-control scheme. In addition, these devices offer optimum performance at low duty cycles by utilizing valley current-mode control architecture. This allows the ADP1870 / ADP1871 to drive all N-channel power stages to regulate output voltages as low as 0.6 V.The ADP1871 is the power saving mode (PSM) version of the device and is capable of pulse skipping to maintain output regulation while achieving improved system efficiency at light loads (see the Power Saving Mode (PSM) Version (ADP1871) section for more information).Available in three frequency options (300 kHz, 600 kHz, and 1.0 MHz, plus the PSM option), the ADP1870 / ADP1871 are well suited for a wide range of applications that require a single-input power supply range from 2.95 V to 20 V. Low voltage biasing is supplied via a 5 V internal LDO.In addition, an internally fixed soft start period is included to limit input in-rush current from the input supply during startup and to provide reverse current protection during soft start for a precharged output. The low-side current-sense, current-gain scheme and integration of a boost diode, along with the PSM/forced pulse width modulation (PWM) option, reduce the external part count and improve efficiency.The ADP1870 / ADP1871 operate over the -40?C to +125?C junction temperature range and are available in 10-lead MSOP package.

The third generation of SHARC®­ Processors, which includes the ADSP-21375 and ADSP-21371, offers increased performance, audio and application-focused peripherals, and memory configurations capable of supporting surround-sound decoder algorithms. All devices are pin-compatible and completely code-compatible with other SHARC Processors such as the ADSP-21367 and ADSP-21369. These members of the SHARC Processor family are based on a single-instruction, multiple-data (SIMD) core, which supports both 32-bit fixed-point and 32-/40-bit floating-point arithmetic formats making them particularly suitable for high-performance audio applications.The ADSP-21371 offers a high performance at a very low cost 266 MHz/1596 MFLOPs -- within the third generation SHARC Processor family. This level of performance makes the ADSP-21371 particularly well suited to address the increasing requirements of the professional and automotive audio market segments while maintaining a low cost. In addition to its higher core performance, the ADSP-21371 includes additional value-added peripherals such as an S/PDIF transmitter/receiver. The ADSP-21371 also provides a direct interface to synchronous SDRAMs with a 32-bit interface that operates at 133 MHz.Third generation SHARC Processors also integrate application-specific peripherals designed to simplify hardware design, minimize design risks, and ultimately reduce time to market. Grouped together, and broadly named the Digital Audio Interface (DAI), these functional blocks may be connected to each other or to external pins via the software-programmable Signal Routing Unit (SRU). The SRU is an innovative architectural feature that enables complete and flexible routing amongst DAI blocks. Peripherals connected through the SRU include but are not limited to serial ports, SPI ports, and S/PDIF Tx/Rx.DEDICATED AUDIO COMPONENTS ADSP-21371—S/PDIF-compatible digital audio receiver/transmitter ADSP-21371—8 dual data line serial ports that operate at up to 33 Mbps on each data line — each has a clock, frame sync, and two data lines that can be configured as either a receiver or transmitter pair 16 PWM outputs configured as four groups of four outputs ROM-based security features include JTAG access to memory permitted with a 64-bit key Protected memory regions that can be assigned to limit access under program control to sensitive code PLL has a wide variety of software and hardware multiplier/divider ratios Available in a 208-lead LQFP_EP package

These devices are capable of operating across a wide voltage range, supporting both dual supply operation at ±10.5 V to ±16.5 V and single supply operation at +21 V to +33 V, while ensuring less than 1% end-to-end resistor tolerance error and offering 20-time programmable (20-TP) memory.The guaranteed industry leading low resistor tolerance error feature simplifies open-loop applications as well as precision calibration and tolerance matching applications.The AD5291 and AD5292 device wiper settings are controllable through the SPI digital interface. Unlimited adjustments are allowed before programming the resistance value into the 20-TP memory. The AD5291 and AD5292 do not require any external voltage supply to facilitate fuse blow, and there are 20 opportunities for permanent programming.
