• ssm2166

    Hi all

    I am using SSM2166 in my audio circuit.

    The datasheet has graphs of

      Figure 5. Noise Gate vs. RGATE (Pin 9 to V+)         NOISE GATE in y axis and RGATE in x axis.

      Figure 9. Rotation Point vs. RROT PT (Pin 11 to V+)   ROTATION POINT in y axis and RROT…

  • hissing noise by SSM2166


    I have interfaced SSM2166 circuit with my audio circuit to limit the audio level. When I feed audio input ,output from ssm2166 gives some hiss sound. But without SSM2166 my old circuit has clean audio output and there is no hiss sound. There is no…

  • i am looking for suitable replacement for SSM2166 (mic preamp)...pls suggest the best solution

    In our applications we have observed that SSM2166 is vulnerable/susceptible to Radio Emissions (with AM modulation) from near by VHF system. In order to overcome this pls suggest the alternative for SSM2166.....

  • Evaluation board Datasheet

    The SSM2166 datasheets refers to a Evaluation Circuit.
    Is the Evaluation board available for purchase?
    What is its part number?


    Sorry, we do not have eval board for SSM2166 anymore. We will revise the
    datasheet. Additionally, for…
  • RE: SSM2166 maximum input voltage

    Hi, Joven

    SSM2166 is internally biased as based on figure 16, and it is expected to be in the level of Vcc/2

    In datasheet says: "A dc voltage of approximately 1.5 V is present at AUDIO +IN (Pin 7)", but this value not equal Vcc/2…

  • Max input level for SSM2166

    Hi, I’m building a bass guitar amplifier and I would like to use a SSM2166 as a limiter just before the class D power amplifier to avoid deep saturation of this stage.

    I’m planning to use a unity gain for the buffer, and a rotation point of 300mVrms…

  • Query re setup of  SSM2166

    Hi, I have several datasheets for this device. Revision F removes all setup info. Revision E appears to have the first two steps of set up reversed. I have a revision B from the Web that makes more sense. Essentially the rotation point set up and VCA…

  • SSM2166 Compression ratio Selection

    We wish to use the compression ratio of 2:1 in our design. In the SSM2166 Datasheet the figure:19 tells to use 8.7KOhms for this. But in the paragraph just above tell that the values proximately 17K Ohms or less will result in 1:1 compression ratio.It…

  • SSM2166 Mute Response Time

    Has anyone looked into how fast the mute function is on the SSM2166 for the implementation shown at Figure 23 of the datasheet (page 11).  My application requires dropping the gain to 0db within 1ms, or better.  Thxs

  • Noise gate setting in SSM2166


    Regarding to noise gate set resistor (pin9) in SSM2166, our customer is asking a question.

    If this resistor will be set 0 ohm, is there any problem in SSM2166?

    They want to connect to GND at noise gate set (pin9) for reducing external parts…
