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 ADAU7112 converts stereo pulse density modulation (PDM) bitstreams into one pulse code modulation (PCM) output stream. The source for the PDM data can be two microphones or other PDM sources. The PCM audio data is output on a serial audio interface port in either inter-IC serial (I2S) or time domain multiplexed (TDM) format. The ADAU7112 is specified over the commercial temperature range (?40?C to +85?C). The ADAU7112 is available in a halide-free, 9-ball, 1.26 mm ? 1.26 mm, 0.4 mm pitch, wafer level chip scale package (WLCSP).Applications?

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.

Demonstration circuit DC675C is for the evaluation of filter circuits using an LT1568. The LT1568 is a dual 2nd order active-RCfilterbuildingblockwithprecision ±0.75% capacitors and low noise op amps with 180MHz GBW trimmed to ±10% maximum variation. The ±10% GBW variation of the LT1568 op amps allows for minimizing the higher frequency error by decreasing resistor values. The cutoff or center frequency (fC) range of an LT1568 filter is 200kHz to 10MHz (5MHz for a bandpass filter). The low limit of 200kHz was chosen only to minimize resistor noise and DC offsets (using external capacitors the fC frequency can be less than 200kHz). For testing and evaluation, the DC675C assembly is configured as a single 4th order, 500kHz narrow passband bandpass filter. For other possible LT1568 configurations, the DC675C has unused pads for 0805 surface mount resistors and capacitors preconfigured with PCB traces to allow for the following high accuracy LT1568 filter circuits: 4th order lowpass filter 5th order lowpass filter 4th order narrow passband bandpass 4th order wide passband bandpass 4th order highpass filter Refer to the LT1568 data sheet for additional information about filter circuit configurations.

The AD8074 /AD8075 are high-speed triple video buffers with a G = +1 and +2 respectively. They operate on ?5V and have a -3dB full signal bandwidth in excess of 500MHz, along with slew rates in excess of 1350V/?s. With better than -80dB of all hostile crosstalk and 90dB isolation, they are useful in many high-speed applications. The differential gain and differential phase error are 0.01% and 0.01?. Gain Flatness of 0.1dB up to 70MHz make the AD8074/75 ideal for RGB buffering or driving. They consume less than 30mA on a ?5V supply voltage.??Both devices offer a high-speed disable feature that allows the outputs to be put into a high impedance state. This allows the building of larger input arrays while minimizing 'OFF' channel output loading. The AD8074/75 are offered in a 16 lead TSSOP package.

The ADMV8432 is a monolithic microwave integrated circuit (MMIC), tunable band-pass filter that features a user selectable pass-band frequency. The 3 dB filter bandwidth is >17% of the center frequency (fCENTER). Additionally, fCENTER can be varied between 16.6 GHz to 30.1 GHz by applying an analog tuning voltage between 0 V to 15 V. The usable pass band corner frequencies (fCORNER) span from 15.1 GHz to 32 GHz. This tunable filter can be used as a much smaller alternative to physically large switched filter banks and cavity tuned filters. This tunable filter has excellent microphonics due to the monolithic design and provides a dynamically adjustable solution in advanced communications applications.APPLICATIONS Test and measurement equipment Military radar and electronic warfare (EW) systems Video satellite (VSAT) communications?
