• RE: AD8062 Sync Stripper

    R2 should be 10k.  See AD8062 data sheet Figure 53



    AD8062 can operate with +/-2.5V because its total supply range is 5V which is the typical operating voltage range. You can use unbalanced supplies like +2.7V and -2.3V, +3V and -2V, +4V and -1V as long it is within the required range of 5V. For 8V…

  • AD5781 VREFNF can not be setted to 0V.

    Dear Engineer:


       I connect the AD8062AR to the AD5781ARUZ by following the instruction of AD5781ARUZ. What I want to achieve is to make the VREFNF to 0V. The diagram about negative connection is shown in below:

  • RE: ADL5513 and 1090Mhz

    The schematic I have is exactly like on page 21 of the data sheet. We are using eval boards for all the devices. This includes the AD8062, ADL5513, and ADL5530. We are connecting the eval board using RF cables.

  • RE: about AD828 Video OPAMP

    Assuming you need a closed loop gain of 2 or thereabouts, you could look at the AD8002, AD8008, AD8056, AD8062, EL2260, LT1819, MAX4216 or OPA2658.

    ICs do not get discontinued in a First-In-Last-Out way, so you can't be sure that an old device like the…

  • ADV7393 and AD725 Interface


    I'm working with ADV7393 and AD725 for RGB to Y/C video output.

    During the design phase i thought the sync pulse is comes only on Green(G) color input signal.

    So i stripped the sync pulse by using the AD8062 only on green color and feed to…

  • ad4897 spice model prooblem

    I downloaded the ad4897 spice model to use in a simulattion of a 2nd order 3.6 MHz LPF.

    I use LtSpice.

    The model would not run until I commented out the BF value for the npn model. (BF= -45455.5454545455).

    Then, the model ran, but gave strange looking…
