The ADAU1701 is a complete single-chip audio system with a 28-/56-bit audio DSP, ADCs, DACs, and microcontroller-like control interfaces. Signal processing includes equalization, cross-over, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening. This processing can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, providing dramatic improvements in perceived audio quality.Its signal processing is comparable to that found in high end studio equipment. Most processing is done in full 56-bit, double precision mode, resulting in very good low level signal performance. The ADAU1701 is a fully programmable DSP. The easy to use SigmaStudio™ software allows the user to graphically configure a custom signal processing flow using blocks such as biquad filters, dynamics processors, level controls, and GPIO interface controls.ADAU1701 programs can be loaded on power-up either from a serial EEPROM through its own self-boot mechanism or from an external microcontroller. On power-down, the current state of the parameters can be written back to the EEPROM from the ADAU1701 to be recalled the next time the program is run.Two Σ-Δ ADCs and four Σ-Δ DACs provide a 98.5 dB analog input to analog output dynamic. Each ADC has a THD + N of −83 dB, and each DAC has a THD + N of −90 dB. Digital input and output ports allow a glueless connection to additional ADCs and DACs. The ADAU1701 communicates through an I2C® bus or a 4-wire SPI port.APPLICATIONS Multimedia speaker systems MP3 player speaker docks Automotive head units Minicomponent stereos Digital televisions Studio monitors Speaker crossovers Musical instrument effects processors In-seat sound systems (aircraft/motor coaches)

The ADM1191 is an integrated current sense amplifier that offers digital current and voltage monitoring via an on-chip, 12-bit analog-to-digital converter (ADC), communicated through an I2C interface. An internal current sense amplifier senses voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin.An industry-standard I2C interface allows a controller to read current and voltage data from the ADC. Measurements can be initiated by an I2C command or via the convert (CONV) pin. The CONV pin is especially useful for synchronizing reads on multiple ADM1191 devices. Alternatively, the ADC can run continuously, and the user can read the latest conversion data whenever it is required. Up to 16 unique I2C addresses can be created, depending on the way the A0 pin and the A1 pin are connected.A SETV pin is also included. A voltage applied to this pin is internally compared to the output voltage on the current sense amplifier. The output of the SETV comparator asserts when the current sense amplifier output exceeds the SETV voltage. When this event occurs, the ALERTB output asserts.The ALERTB output can be used as a flag to warn a micro-controller or field programmable gate array (FPGA) of an overcurrent condition. ALERTB outputs of multiple ADM1191 devices can be tied together and used as a combined alert.The ADM1191 is packaged in a 10-lead MSOP.APPLICATIONS Power monitoring/power budgeting Central office equipment Telecommunication and data communication equipment PCs/servers

The Blackfin® Processor family has been expanded to address the ever-increasing need for pervasive embedded network connectivity with two new family members. This connectivity is powerful when utilized in conjunction with the high performance 16-/32-bit Blackfin embedded processor core, the flexible cache architecture, the enhanced DMA subsystem, and the Dynamic Power Management (DPM) functionality. System designers can take advantage of the combined control and signal processing capabilities of the processor core across a wide range of end applications through the scalability of the pin and code compatibility of these new family members. The ADSP-BF536 and ADSP-BF537 are a functional extension of the popular ADSP-BF531 / ADSP-BF532 / ADSP-BF533 processors, and they are ideally suited for a variety of networked applications. The ADSP-BF537 is the higher performance series member, with more embedded memory enabling higher throughput needs for embedded applications suchas video security/surveillance and industrial-environment-based distributed control/factory automation applications. The ADSP-BF536 offers exceptional performance and is designed for low cost connected devices such as remote monitoring devices, VoIP, point-of-saleterminals, and biometrics/security applications. Both devices are ideally suited for a broad range of industrial, instrumentation, medical, and consumer appliance applications— allowing for scalability based upon the required network bandwidth and mix of control, plus signal processing needed in the end product.

The ADN8833 is a monolithic H-bridge TEC driver with integrat-ed 1 A power MOSFETs. It has a linear power stage with the linear driver (LDR) output and a pulse-width modulation (PWM) power stage with the SW output. Depending on the control voltage at the CONT input, the ADN8833 drives current through a TEC to settle the temperature of a laser diode or a passive component attached to the TEC module to the programmed target temperature.The control voltage applied to the CONT input is generated by a digital-to-analog converter (DAC) closing the digital proportional, integral, derivative (PID) loop of temperature control system.The internal 2.5 V reference voltage provides a 1% accurate output that is used to bias a voltage divider network to program the maximum TEC current and voltage limits for both the heating and cooling modes. It can also be a reference voltage for the DAC and the temperature sensing circuit, including a thermistor bridge and an analog-to-digital converter (ADC).APPLICATIONS TEC temperature control Optical modules Optical fiber amplifiers Optical networking systems Instruments requiring TEC temperature control

The AD7891 is an 8-channel, 12-bit data acquisition system with a choice of either parallel or serial interface structure. The part contains an input multiplexer, an on-chip track/hold amplifier, a high speed 12-bit ADC, a 2.5 V reference, and a high speed interface. The part operates from a single 5 V supply and accepts a variety of analog input ranges across two models, the AD7891-1 (±5 V and ±10 V) and the AD7891-2 (0 V to +2.5 V, 0 V to +5 V, and ±2.5 V).The AD7891 provides the option of either a parallel or serial interface structure determined by the MODE pin. The part has standard control inputs and fast data access times for both the serial and parallel interfaces, ensuring easy interfacing to modern microprocessors, microcontrollers, and digital signal processors.In addition to the traditional dc accuracy specifications, such as linearity, full-scale and offset errors, the part is also specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio.Power dissipation in normal mode is 82 mW typical; in the standby mode, this is reduced to 75 mW typ. The part is available in a 44-terminal MQFP and a 44-lead PLCC.PRODUCT HIGHLIGHTS The AD7891 is a complete monolithic 12-bit data acquisition system that combines an 8-channel multiplexer, 12-bit ADC, 2.5 V reference, and track/hold amplifier on a single chip. The AD7891-2 features a conversion time of 1.6 ms and an acquisition time of 0.4 ms. This allows a sample rate of 500 kSPS when sampling one channel and 62.5 kSPS when channel hopping. These sample rates can be achieved using either a software or hardware convert start. The AD7891-1 has an acquisition time of 0.6 ms when using a hardware convert start and an acquisition time of 0.7 ms when using a software convert start. These acquisition times allow sample rates of 454.5 kSPS and 435 kSPS, respectively, for hardware and software convert start. Each channel on the AD7891 has overvoltage protection. This means an overvoltage on an unselected channel does not affect the conversion on a selected channel. The AD7891-1 can withstand overvoltages of ±17 V.APPLICATIONS Data Acquisition Systems Motor Control Mobile Communication Base Stations Instrumentation
