Hi there, According to data sheet NX3L4051: Single low-ohmic 8-channel analog switch (REV 5.1) and according to table 12 , there is presented that: simbol: f(-3dB) , (-3 dB frequency response) , for conitions VCC = 1.4 V to 4.3 V , is typically 15 - MHz Because therre is no frequence response graphics presented, My Question is how much signal attenuation from input to output can I expect for a signal of 13.56 MHz frequency and how much is that data consistent between switches and how crosstalk is influeced by? Thanks a lot, Dragan Vasic vasic.dragan51@gmail.com
