The ADuM3480 / ADuM3481 / ADuM3482 are quad-channel digital isolators based on the Analog Devices, Inc.,iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as optocoupler devices and other integrated couplers. With typical propagation delay reduced to 25 ns, pulse width distortion is also halved.The four channels of the ADuM3480 / ADuM3481 / ADuM3482 are available in a variety of channel configurations with two data rate grades up to 25 Mbps (see the Ordering Guide section). All models use separate core and I/O power supplies. The core operates between 3.0 V and 5.5 V, whereas the I/O supply can range from 1.8 V to 5.5 V. If operation is required within the range of the core supply, the two supplies can be tied together to allow single-supply operation. When the I/O must interface with logic levels that are different from the core supply voltage, then the I/O supply can be operated independently of the core supply over a wider range. The minimum I/O supply voltage is 1.8 V, allowing compatibility with low voltage logic. Both core and I/O supplies are required for proper operation.APPLICATIONS General-purpose multichannel isolation SPI interface/data converter isolation Industrial field bus isolation

The ADuM7640 / ADuM7641 / ADuM7642 / ADuM7643 are 6-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. These 1 kV digital isolation devices are packaged in a small 20-lead QSOP.

The SSM3302 is a fully integrated, high efficiency, stereo Class-D audio amplifier. The application circuit requires minimal externalcomponents and operates from a single 7 V to 18 V supply. The device is capable of delivering 2 × 10 W of continuous output power into a 4 Ω load (or 2 × 8 W into 8 Ω) with 98 dB. Spread spectrum pulse density modulation (PDM) is used toprovide lower EMI radiated emissions compared with other Class-D architectures. The SSM3302 includes an optional modulation select pin (ultralow EMI emission mode) that significantly reduces the radiated emissions at the Class-D outputs, particularly above 100 MHz. The SSM3302 can pass FCC Class-B emissions testing with an unshielded 20 inch cable using common-mode choke-based filtering.The fully differential input of the SSM3302 provides excellent rejection of common-mode noise on the input. The device also includes a highly flexible gain select pin that only requires one series resistor to choose a gain between 9 dB and 24 dB, with no change to the input impedance. The benefit of this is to improve gain matching between multiple SSM3302 devices within a single application compared with using external resistors to set gain.The SSM3302 includes an integrated voltage regulator thatgenerates a 5 V rail.The SSM3302 has a micropower shutdown mode with a typical shutdown current of 10 μA. Shutdown is enabled by applying a logic low to the SD pin. The device also includes pop-and-click suppression circuitry that minimizes voltage glitches at the output during turn on and turn off, reducing audible noise during activation and deactivation.Other included features to simplify system level integration of the SSM3302 are input low-pass filtering to suppress out-ofband DAC noise interference to the pulse density modulator, fixed input impedance to simplify component selection across multiple platform production builds, and a thermal warning indicator pin.The SSM3302 is specified over the commercial temperaturerange (−40°C to +85°C). It has built-in thermal shutdown andoutput short-circuit protection.

The ADAU1452 / ADAU1451 / ADAU1450 are automotive qualified audio processors that far exceed the digital signal processing capabilities of earlier SigmaDSP® devices. The restructured hardware architecture is optimized for efficient audio processing. The audio processing algorithms are realized in sample-by-sample and block-by-block paradigms that can both be executed simultaneously in a signal processing flow created using the graphical programming tool, SigmaStudio™. The restructured digital signal processor (DSP) core architecture enables some types of audio processing algorithms to be executed using significantly fewer instructions than were required on previous SigmaDSP generations, leading to vastly improved code efficiency.The 1.2 V, 32-bit DSP core can run at frequencies of up to 294.912 MHz and execute up to 6144 instructions per sample at the standard sample rate of 48 kHz. 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
