• AD8145

    What is the maximum input voltage for the AD8145 when operating with a supply voltage of 5V? The absolute maximum rating only lists 12V for the supply voltage.

  • AD8145

    Hi,

    1. I want to know which clamping method [Differential clamping or common mode clamping] should I use for my RGB STANAG 3350B differential video input coming as input to AD8145 and why that particular clamping method only? 

    Note that the video waveform…

  • AD8145 doesn't work exactly.

    Dear Sir/Madam,

    I need your help.

    My schematic:

    cf5b8619e13a6629748eb9fcb37b1341.bin

    VREF is provided directly by AD5765. I set the common mode voltage of Vin to 0.5 V and the differential mode voltage to 1.0 V.

    AD5765's output voltage is set to…

  • AD8145 power-down

    Hello,

    I want to put the AD8145 into power-down. I use +5V / -5V for power supply.

    1.) The datasheet says the AD8145 will enter power-down when the voltage applied to the power-down pin drops to approximately 2 V below the positive supply. I assume…

  • AD8145 Single Supply Question

    Hello,

    I would like to use the AD8145 on a single 5V supply. I did not find a reference schematic on how to do that.

    Is it correct, that I

    - connect VS+ to 5V

    - connect VS- to 0V

    - GND-Pins to 0V

    - use a 2.5V bias (e.g. via 100k) for the (AC coupled…

  • AD8145 comparators schematic design

    Hello

    I read the AD8143-EVALZ_AD8145-EVALZ_UG-862.pdf ,and I am confused about the figure 3 in page 6

    1、Why connect  R_CM,B_CM,G_CM to VCC and VEE via resistance ,such as  R53,R56,R54,R55,R61,R62

    2、Why use R32,R33,R51

    I dont see the  resistance above in AD8145…

  • AD8145使用问题

    电路图如下:


    其中Vref 由ADI的DAC芯片AD5765输出端直接提供,VIN施加共模为0.5 V,差模为1.0V的差分信号

    预设AD5765输出电压为0 V.

    实验中,我测试芯片AD8145的REF引脚,发现该电压并不是AD5765预设的电压值(当然此时,AD5765输出电压跟REF端几乎相等,显然不正常)REF端输出一个与VIN同频的信号,且其峰峰值随VIN的频率变化如下:

    及其对数坐标表示:

    我的问题是:

    REF端之所以不跟随AD5765,是因为AD5765的驱动能力不足造成的吗…

  • AD8145 & ADV3201- Negative supply voltage

    Hello,

    AD8145 operates from +5V & -5V

    ADV3201 operates from +3.3V & -3.3V

    In case without negative supply powered on the both the IC's, What will happen the IC?

    What is the maximum delay can maintain for both supplies are raise?
