  • RE: ADC3441: "input pin (...) must swing symmetrically", ADC344x family

    Christoph, I am sorry but I do not understand your question. Maybe if you can describe SiPM in more detail as I am unfamiliar with this. Do you have a schematic you can share? What is exactly driving the ADC input pins? Regards, Jim

  • RE: ADC3441: Digital Inputs support 1.8V and 3.3V logic levels but but why not 2.5V?

    Resolved
    Hi Yves, Yes, you can use 2.5V for the SPI pins. Please keep in mind that DVDD is 1.8V, so when the ADC3441 is talking back on the SPI bus, the output will be 1.8V translated. I would make sure that the VOH/VOL of the ADC3441 are compatible with the…

  • ADC3441: what is the minimum input frequency capability of the device?

    Part Number: ADC3441 Other Parts Discussed in Thread: THS4552 The data sheet and typical graphs specs dowm to 10MHz, but does the part work to lower frequencies (but with lower performance) alternatively is there a baseband sampling version?

  • RE: High speed ADC with an integrated multiplexer at the input

    Resolved
    Hi Obinna, We do not have a high speed ADC (10MSPS+) that incorporates an integrated mux. The closest thing I can think of is a part like the ADC3421 (12 bit) or ADC3441 (14 bit), but these have independent inputs for each channel. What application…
