However, in addition to industry-standard rates, a wide range of sample rates are available. The integer PLL and flexible clock generator hardware can generate up to 15 audio sample rates simultaneously. These clock generators, along with the on-board asynchronous sample rate converters (ASRCs) and a flexible hardware audio routing matrix, make the ADAU1452 / ADAU1451 / ADAU1450 ideal audio hubs that greatly simplify the design of complex multirate audio systems.The ADAU1452 / ADAU1451 / ADAU1450 interface with a wide range of analog-to-digital converters (ADCs), digital-to-analog converters (DACs), digital audio devices, amplifiers, and control circuitry, due to their highly configurable serial ports, S/PDIF interfaces (on the ADAU1452 and ADAU1451), and multipurpose input/output pins. The devices can also directly interface with pulse density modulation (PDM) output microelectromechanical (MEMS) microphones, due to integrated decimation filters specifically designed for that purpose.Independent slave and master I2C/serial peripheral interface (SPI) control ports allow the ADAU1452 / ADAU1451 / ADAU1450 not only to be programmed and configured by an external master device, but also to act as masters that can program and configure external slave devices directly. This flexibility, combined with self boot functionality, enables the design of standalone systems that do not require any external input to operate.The power efficient DSP core executes full programs, consumes only a few hundred milliwatts (mW) of power, and can run at a maximum program load while consuming less than a watt, even in worst case temperatures exceeding 100?C. This relatively low power consumption and small footprint make the ADAU1452 / ADAU1451 / ADAU1450 ideal replacements for large, general-purpose DSPs that consume more power at the same processing load.Differences between the ADAU1452, ADAU1451, and ADAU1450The five variants of this device are differentiated by memory, DSP core frequency, availability of S/PDIF interfaces, ASRC configuration, and temperature range.Because the ADAU1450 does not contain an S/PDIF receiver or transmitter, the SPDIFIN and SPDIFOUT pins are nonfunctional. Additionally, the settings of any registers related to the S/PDIF input or output in the ADAU1450 do not have any effect on the operation of the device.Because the ADAU1450 does not contain ASRCs, the settings of any registers related to the ASRCs in the ADAU1450 do not have any effect on the operation of the device.APPLICATIONS Automotive audio processing Head units Navigation systems Rear seat entertainment systems DSP amplifiers (sound system amplifiers) Commercial and professional audio processing Consumer audio processing

EVAL-ADBMS6830MSW
Analog Devices Inc.The ADBMS6830 is a multicell battery stack monitor that measures up to 16 series connected battery cells with a lifetime total measurement error (TME) of less than 2 mV over the full temperature range. The measurement input range of ?2 V to +5.5 V makes the ADBMS6830 suitable for most battery chemistries and allows measurement of voltages across bus bars. Provisions are made for bypassing bus bars without dedicating any measurement channels.All cells can be measured simultaneously and redundantly with two individual analog-to-digital converters (ADCs). The continuously operating ADCs with a high sampling rate of 4.096 MHz allow reduced external analog filtering and aliasing free measurement results. Higher noise reduction can be achieved by subsequent programmable infinite impulse response (IIR) filters.Multiple ADBMS6830s can be connected in series, permitting simultaneous cell monitoring of long, high voltage battery strings.Each ADBMS6830 has an isolated serial port interface (isoSPI?) for high speed, RF immune, long distance communications. Multiple devices are connected in a daisy chain with one host processor connection. This daisy chain can be operated bidirectionally, ensuring communication integrity even in the event of a fault along the communication path.The ADBMS6830 can be powered from the battery stack or an isolated supply. The ADBMS6830 includes passive balancing with individual pulse-width modulation (PWM) duty cycle control and up to 300 mA discharge current for each cell. Other features include an on-board 5 V regulator, up to 10 general-purpose inputs/outputs, and a sleep mode, where current consumption is reduced to 4 ?A.APPLICATIONS Electric and hybrid electric vehicles Backup battery systems Grid energy storage
EVAL-ADCMP561BRQZ
Analog Devices Inc.The ADCMP561/ADCMP562 are high speed comparators fabricated on Analog Devices, Inc., proprietary XFCB process. The devices feature a 700 ps propagation delay with less than 75 ps overdrive dispersion. Dispersion, a measure of the difference in propagation delay under differing overdrive conditions, is a particularly important characteristic of comparators. A separate programmable hysteresis pin is available on the ADCMP562.A differential input stage permits consistent propagation delay with a wide variety of signals in the common-mode range from ?2.0 Vto +3.0 V. Outputs are complementary digital signals that are fully compatible with PECL 10 K and 10 KH logic families. The outputs provide sufficient drive current to directly drive transmission lines terminated in 50 ? to VDD ? 2 V. A latch input, which is included, permits tracking, track-and-hold, or sample-and-hold modes of operation. The latch input pins contain internal pull-ups that set the latch in tracking mode when left open.The ADCMP561/ADCMP562 are specified over the industrial temperature range (?40?C to +85?C).Applications Automatic test equipment High speed instrumentation Scope and logic analyzer front ends Window comparators High speed line receivers Threshold detection Peak detection High speed triggers Patient diagnostics Disk drive read channel detection Hand-held test instruments Zero-crossing detectors Line receivers and signal restoration Clock drivers
