The ADA④③⓪②-④ is used as an active element in applications where a lossless signal split is required. Typical applications include multituner cable set-top boxes, cable splitter modules, multituner televisions, and home gateways where traditional solutions have consisted of discrete passive splitters followed by separate fixed gain amplifiers. The ADA④③⓪②-④ is a low cost alternative solution that simplifies designs and improves system performance by integrating a signal splitter element and gain element into a single IC solution.
The AD⑧③⑦⑤ is a digitally controlled, variable gain, wide bandwidth amplifier that provides precise gain control, high IP③, and low noise figure. The excellent distortion performance and high signal bandwidth make the AD⑧③⑦⑤ an excellent gain control device for a variety of receiver applications. Using an advanced high speed SiGe process and incorporating proprietary distortion cancellation techniques, the AD⑧③⑦⑤ achieves ⑤⓪ dBm output IP③ at ②⓪⓪ MHz.
Analog Devices, Inc.,《ADI数模转换器IC的设计方案》,国模拟器件公司(AnalogDevices,Inc.,纽约证券交易所代码:ADI),全球领先的高性能信号处理应用解决方案供应商,今日在马萨诸塞州诺伍德市(Norwood,Mass.)发布具有内置①④bit数模转换器(DAC)的直接数字频率合.
The AD⑨⑧⑦⑨ is a single supply Cable Modem/Set Top Box Mixed Signal Front End. The device contains a transmit path interpolation filter, a complete quadrature digital upconverter and transmit DAC. The receive path contains a ①②-bit ADC, a ①⓪-bit ADC, and Dual ⑦-bit ADCs. All internally required clocks and an output system clock are generated by the PLL from a single crystal or clock input.
The AD⑤③③⑦/AD⑤③③⑧/AD⑤③③⑨ are dual ⑧-, ①⓪-, and ①②-bit buffered voltage output DACs, respectively. Each part is housed in an ⑧-lead MSOP package and operates from a single 2.5 V to ⑤.⑤ V supply, consuming ②⑤⓪ A at ③ V. On-chip output amplifiers allow rail-to-rail output swing with a slew rate of ⓪.⑦ V/s. A ②-wire serial interface operates at clock rates up to ④⓪⓪ kHz. This interface is SMBus compatible at VDD ③.⑥ V. Multiple devices can be placed on the same bus.
The AD①⑨③⑦ is a high performance, single-chip codec that provides four analog-to-digital converters (ADCs) with differential input and eight digital-to-analog converters (DACs) with differential output, using the Analog Devices, Inc., patented multibit sigma-delta (-) architecture. An I②C port is included, allowing a microcontroller to adjust volume and many other parameters. The AD①⑨③⑦ operates from ③.③ V digital and analog supplies. The AD①⑨③⑦ is available in a ⑥④-lead (differential output) LQFP.
The SSM②⓪①⑨ is a latest generation audio preamplifier, combining SSM preamplifier design expertise with advanced processing. The result is excellent audio performance from a monolithic device, requiring only one external gain set resistor or potentiometer. The SSM②⓪①⑨ is further enhanced by unity gain stability.
The AD⑤③⓪①/AD⑤③①①/AD⑤③②①* are single ⑧-/①⓪-/①②-bit, buffered, voltage-output DACs that operate from a single 2.5 V to ⑤.⑤ V supply, consuming ①②⓪ A at ③ V. The on-chip output amplifier allows rail-to-rail output swing with a slew rate of ⓪.⑦ V/s. It uses a ②-wire (I②C-compatible) serial interface that operates at clock rates up to ④⓪⓪ kHz. Multiple devices can share the same bus.
The AD⑧③②⓪ is a digitally controlled variable gain amplifier optimized for coaxial line driving applications. An ⑧-bit serial word determines the desired output gain over a ③⑥ dB range (②⑤⑥ gain levels). The AD⑧③②⓪ provides linear gain response.
The AD⑧⑥①①/AD⑧⑥①② are single and dual ④ ns comparators with latch function and complementary output. The latch is not functional if VCC is less than ④.③ V. Fast ④ ns propagation delay makes the AD⑧⑥①①/AD⑧⑥①② good choices for timing circuits and line receivers. Propagation delays for rising and falling signals are closely matched and tracked over temperature. This matched delay makes the AD⑧⑥①①/AD⑧⑥①② good choices for clock recovery because the duty cycle of the output matches the duty cycle of the input
