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!

Is there an LT1564 model or device for use in LTspice?

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)
