  • 运算放大器稳定时间的测量

    The AN10 begins with a survey of methods for measuring op amp settling time. This commentary develops into circuits for measuring settling time to 0.0005%. Construction details and results are presented. Appended sections cover oscilloscope overload limitations and amplifier frequency compensation.

  • 基于微处理器的5V系统接口

    This application note discusses a variety of approaches for interfacing analog signals to 5V powered systems. Synthesizing a "rail-to-rail" op amp and scaling techniques for A/D converters are covered. A voltage-to-frequency converter, applicable where high resolution is required, is also presented.

    his folder contains the following files: 1. 02490rxP802-15_SG3a-Channel-Modeling-Subcommittee-Report-Final.doc: This is the final report of the channel modeling sub-committee. 2. cmx_imr.csv (x=1, 2, 3, and 4) represent the files containing the actual 100 channel realizations for CM1, CM2, CM3, and CM4. The columns are organized as (time, amp, time, amp,...) 3. cmx_imr_np.csv (x=1, 2, 3, and 4) represent the files containing the number of paths in each of the 100 multipath realizations. 4. cmx_imr.mat (x=1, 2, 3, and 4) are the .mat files that can be loaded directly into Matlab (TM). 5. *.m files are the Matlab (TM) files used to generate the various channel realizations.

    LCD Driver datasheet The SPF54126A, a 262144-color System-on-Chip (SoC) driver LSI designed for small and medium sizes of TFT LCD display, is capable of supporting up to 176xRGBx220 in resolution which can be achieved by the designated RAM for graphic data. The 528-channel source driver has true 6-bit resolution, which generates 64 Gamma-corrected values by an internal D/A converter. The source driver of SPFD54126A adopts OP-amp structure to enhance display quality and it cooperates with advanced circuitry techniques to reduce power consumption.

  • 随着家用电器种类的增多

    随着家用电器种类的增多, 遥控器的种类也随之增多, 由于不同种类的遥控器不能相互代替, 这给人们的生活带来些不便.若能有一种万能遥控器, 它可同时控制不同类型的TV、 VCR、CBL、DVD、VCD、amp、CD、TAPE、TUNER等, 并且价格与现在的专用遥控器价格相当, 这将方便人们的生活, 改善人们的生活素质.
