The ADSP-21160M DSP is a SHARC processor that is optimized for applications such as telephony, medical imaging, radar/sonar electronics, communications, 3D graphics and imaging. The ADSP-21160M features a Single-Instruction-Multiple-Data (SIMD) architecture.Using two computational units (ALU, Barrel Shifter, MAC, Register files), the ADSP-21160M can have a five fold performance increase versus the ADSP-2106x on a range of DSP algorithms. It is code compatible with ADI's popular first generation ADSP-2106x SHARC DSPs. Like other SHARCs, the ADSP-21160M is a 32-bit processor that is optimized for high performance DSP applications. The ADSP-21160M includes an 80 MHz core for processing both 32-bit fixed-point and (32-bit, 40-bit) floating-point data types, a dual-ported 4 Mbit on-chip SRAM, an integrated I/O processor with multiprocessing support, and multiple internal busses to eliminate I/O bottlenecks.The ADSP-21160M is optimized for multiprocessing topologies; SHARC supports multiprocessing via link ports or an external port. In the diagram below, both cluster and link port multiprocessing is shown. Over the external port up to six 21160Ms may be connected together without any additional support logic. The arbitration for this shared bus is integrated on-chip. Each SHARC in the cluster has access to every SHARC's internal memory. Through the external port connection, optional external memory may be shared as well.The six link ports are another way to gluelessly connect a multiprocessing system. Both, the links and the cluster can be used simultaneously and systems with hundreds of SHARC DSPs can be developed using both peripherals.Maximize Speed, Minimize Size The ADSP-21160M is offered in a 27mm x 27mm 400-ball PBGA (Plastic Ball Grid Array) package 40% smaller than processors in this performance class.More Processing Per WattIn addition to small size and high performance, the 21160M's power dissipation enables new levels of MFLOPS per watt. The ADSP-21160M typical power dissipation is 2 watts, enabling 240 MFLOPS of performance per watt. This allows designers to use multiple processors on a PCI card within the PCI power limit of 25 watts. With eight 21160M DSPs, providing 480 MFLOPS each, a standard PCI card design can obtain 3.84 GFLOPS performance and leave 9 watts for other circuitry.The ADSP-21160M is supported by hundreds of readily available third-party hardware and software products and ADI's powerful VisualDSP++ development system, allowing for fast and easy development, debug and deployment.

The DAC-8228 is a dual 8-bit, voltage output, CMOS, D/A converter in a single chip. It was designed to drop into AD7528 / AD7628 sockets eliminating two external op amps in applications such as hard diskdrives. These applications generally operate the AD7528 / AD7628 with zero volts applied to VREF and offset AGND to +2.5 or +5 volts. The DAC-8228 is tested under both these conditions.The DAC-8228 can also be used in those applications requiring a unipolar output voltage. It can deliver an output voltage between 0V and +10V with VDD = +14V (maximum output voltage is VDD -4V). The DAC-8228's reference input can accept a negative voltage from 0V to -10V (the DAC's internal unity-gain inverting amplifier inverts the input signal). Choose the DAC-8229 for bipolar operation.The DAC8228 offers CerDIP and plastic packaged devices in the extended industrial temperature range of -40° to +85°C. Applications requiring the military temperature range should use the DAC-8229. To make the DAC-8229 pin and functionally compatible with the DAC-8228, AGND A and AGND B should be tied together to function as VZ, and VSS connected to GND.The DAC-8228 consists of two CMOS voltage output amplifiers, two high-accuracy R-2R resistor ladder networks, interface control logic, and two 8-bit registers. An internal regulator maintains TTL logic compatibility and fast microprocessor interface timing over the full VDD range.The DAC-8228 dissipates only 90mW in the space saving 20-pin 0.3' DIP or the 20-lead SO surface mount package. Its compact size, low power, and economical cost per channel, makes it attractive for applications requiring multiple D/A converters without sacrificing circuit-board space. Reduced parts count also improves system reliability.Using PMI's advanced oxide-isolated, silicon-gate CMOS process, coupled with its highly-stable thin-film resistor ladder, allows the DAC-8228 to offer superior matching and temperature tracking between DACs.APPLICATIONS Disk Drive Systems Automatic Test Equipment Process/Industrial Controls Energy Controls Programmable Instrumentation Multi-Channel Microprocessor-Controlled Systems Servo Control Systems

The AD5235 is a dual-channel, nonvolatile memory, digitallycontrolled potentiometer with 1024-step resolution, offeringguaranteed maximum low resistor tolerance error of ±8%.The device performs the same electronic adjustment functionas a mechanical potentiometer with enhanced resolution, solidstate reliability, and superior low temperature coefficient performance.The versatile programming of the AD5235 via anSPI®-compatible serial interface allows 16 modes of operationand adjustment including scratchpad programming, memorystoring and restoring, increment/decrement, ±6 dB/step log taperadjustment, wiper setting readback, and extra EEMEM for user-definedinformation such as memory data for other components,look-up table, or system identification information.In the scratchpad programming mode, a specific setting canbe programmed directly to the RDAC register, which sets theresistance between Terminal W and Terminal A and Terminal Wand Terminal B. This setting can be stored into the EEMEMand is restored automatically to the RDAC register duringsystem power-on.The EEMEM content can be restored dynamically or throughexternal PR strobing, and a WP function protects EEMEMcontents. To simplify the programming, the independent orsimultaneous linear-step increment or decrement commandscan be used to move the RDAC wiper up or down, one step ata time. For logarithmic ±6 dB changes in the wiper setting, theleft or right bit shift command can be used to double or halve theRDAC wiper setting.The AD5235 patterned resistance tolerance is stored in theEEMEM. The actual end-to-end resistance can, therefore, beknown by the host processor in readback mode. The host canexecute the appropriate resistance step through a softwareroutine that simplifies open-loop applications as well asprecision calibration and tolerance matching applications.The AD5235 is available in a thin, 16-lead TSSOP package.The part is guaranteed to operate over the extended industrialtemperature range of −40°C to +85°C.Applications DWDM laser diode driver, optical supervisory systems Mechanical potentiometer replacement Instrumentation: gain, offset adjustment Programmable voltage-to-current conversion Programmable filters, delays, time constants Programmable power supply Low resolution DAC replacement Sensor calibration

The AD5246 provides a compact 2 mm × 2.1 mm packaged solution for 128-position adjustment applications. This device performs the same electronic adjustment function as a variable resistor. Available in four different end-to-end resistance values (5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments.The wiper settings are controllable through the I2C compatible digital interface, which can also be used to read back the present wiper register control word. The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.Operating from a 2.7 V to 5.5 V power supply and consuming 3 μA allows for usage in portable battery-operated applications.APPLICATIONS Mechanical potentiometer replacement in new designs Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Automotive electronics adjustment Gain control and offset adjustment
