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 ?-? ADCs and four ?-? 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 ADAV801 is a stereo audio codec intended for applications such as DVD or CD recorders that require high performance and flexible, cost-effective playback and record functionality. The ADAV801 features Analog Devices, Inc. proprietary, high performance converter cores to provide record (ADC), playback (DAC), and format conversion (SRC) on a single chip. The ADAV801 record channel features variable input gain to allow for adjustment of recorded input levels and automatic level control, followed by a high performance stereo ADC whose digital output is sent to the record interface. The record channel also features level detectors that can be used in feedback loops to adjust input levels for optimum recording. The playback channel features a high performance stereo DAC with independent digital volume control.The sample rate converter (SRC) provides high performance sample rate conversion to allow inputs and outputs that require different sample rates to be matched. The SRC input can be selected from playback, auxiliary, DIR, or ADC (record). The SRC output can be applied to the playback DAC, both main and auxiliary record channels, and a DIT.Operation of the ADAV801 is controlled via an SPI-compatible serial interface, which allows the programming of individual control register settings. The ADAV801 operates from a single analog 3.3 V power supply and a digital power supply of 3.3 V with an optional digital interface range of 3.0 V to 3.6 V.The part is housed in a 64-lead LQFP package and is character-ized for operation over the commercial temperature range of ?40?C to +85?C.APPLICATIONSDVD-recordable All formats CD-R/W Data Sheet, Rev.

The ADE7763 features proprietary ADCs and fixed function DSP for high accuracy over large variations in environmental conditions and time. The ADE7763 incorporates two second-order, 16-bit ?-? ADCs, a digital integrator (on Ch1), reference circuitry, a temperature sensor, and all the signal processing required to perform active and apparent energy measurements, line-voltage period measurements, and rms calculation on the voltage and current channels. The selectable on-chip digital integrator provides direct interface to di/dt current sensors such as Rogowski coils, eliminating the need for an external analog integrator and resulting in excellent long-term stability and precise phase matching between the current and the voltage channels.The ADE7763 provides a serial interface to read data and a pulse output frequency (CF) that is proportional to the active power. Various system calibration features such as channel offset correction, phase calibration, and power calibration ensure high accuracy. The part also detects short duration, low or high voltage variations.The positive-only accumulation mode gives the option to accumulate energy only when positive power is detected. An internal no-load threshold ensures that the part does not exhibit any creep when there is no load. The zero-crossing output (ZX) produces a pulse that is synchronized to the zero-crossing point of the line voltage. This signal is used internally in the line cycle active and apparent energy accumulation modes, which enables faster calibration.The interrupt status register indicates the nature of the interrupt, and the interrupt enable register controls which event produces an output on the IRQ pin, an open-drain, active low logic output.The ADE7763 is available in a 20-lead SSOP package.
