TMUX4827: The characteristics for the input signal 125kHz/10Vpp sinusoidal wave

TOMOHIRO UENO
Prodigy 40 points
Part Number: TMUX4827

Can "TMUX4827" swith the input signal of 125kHz/10Vpp sinusoidal wave?

There are below description in the data sheet.
- Signal path input/output voltage is -12V min and +12V max.
- "–3 dB Bandwidth" is 72MHz typ.
Therefore, we think this device can swith the input signal of 125kHz/10Vpp sinusoidal wave.

    Hello Tomohiro,

    This device cannot actually support  the input signal of 125kHz/10Vpp sinusoidal wave.

    Based on this graph signals that have a swing of 2V or (1Vpp) can sent through the mux. 

    For 10Vpp we will need the signal to operate at a lower frequency to pass through the mux properly.

    1.Is slowing down the input signal an option?

    If we were to slow it down to 50KHZ (based of this graph) I believe your signal will pass through the mux.

    Please let me know what you think?

    Regards

    Dear Kameron,

    Thanks for your quick response!
    We could understand your answer.
    By the way, please teach the conditons to utilize input range from -12V to +12V.
    We think that it is best avbantage of TMUX4827 to be able to treat inpiu voltage from -12V to +12V, exceeding power supply.
    We want know its conditions to get best advantage.

    Best Regard,

    Hello Tomohiro,

    So after speaking with our design team, this device should be able to pass a -12V to +12V signal that is less than 10kHz.

    While this is not on the datasheet we will align internally about how to include on the datasheet in any further datasheet revisions.

    Please let me know if you have any further questions!

    Regards,

    Kameron
