• LTC1564 Input

    Hi all,

    I have a question about the amount of current sink by the input pin (pin 16) on LTC1564 low pass filter. I measured 25 mA current  on the input pin. I would like to know if that is normal. Thanks in advance!

  • RE: ltc1564 LTspice model?

    Hello.

    An LTC1564 LTspice model can be build using ideal 2nd order filter models (small signal).

    The LTspice models symbols and sub circuits must be in the same folder to run an LTC1564 sim.

    Will provide model tomorrow.

  • LTC1564 not working as expected

    Hello,

    I recently purchased LTC1564. I wired it up according to the reference schematic given in the datasheet (Shown below)

    Here are the things I tried

    1. Single supply configuration

        V+ = 5V

        V- = GND

        G3 = G2 = G1 = G0 = 0 (1V/V passband gain)
