MUX36D08: PSRR Specification

Jochen Politze
Prodigy 10 points
Part Number: MUX36D08

Tool/software:

Dear Texas Instruments Support Team,

I am currently evaluating the MUX36D08 analog multiplexer for use in a precision analog circuit that operates across a wide frequency range (1 Hz to 1 MHz) and sources and measures very low to moderate currents (1 nA to 1 mA). This application is highly sensitive to power supply noise, and I am therefore interested in understanding the Power Supply Rejection Ratio (PSRR) characteristics of the MUX36D08.

While reviewing the datasheet and product documentation, I was unable to locate any explicit information about the PSRR or related parameters under varying supply conditions. Could you please provide:

  1. The PSRR specification (or equivalent data) for the MUX36D08 across its recommended supply ranges?

  2. Any internal test results, typical behavior, or application notes that characterize the device’s performance with respect to power supply noise?

  3. Guidance or recommendations for minimizing power supply sensitivity when using this device in high-precision applications?

Your assistance is greatly appreciated. Please let me know if further technical details about the intended application would be helpful.

Best regards,

Jochen

    Hi Jochen,

    Unfortunately we don't have any PSRR data for this device so I won't be able to help provide anything on that front.

    Typically standard practice is to just add some decoupling capacitors to the supply pin to ensure a clean supply. We recommend a 0.1uF and 1uF decoupling capacitors.

    Thanks,
    Rami
