2013-03-30 4:17 am. #9. On all of the soundcards that I have typically 1.12Vp-p is the maximum input level that I can input to the soundcard if the input gain setting in the window control panel is set to its highest level of 100. At lower …

\$\begingroup\$ Any normal DAC should have no problems accepting input from a sound card. The voltage range is more or less standardized. Furthermore, you'll probably be using S/PDIF to connect DAC to soundcard and if the soundcard supports S/PDIF it will be capable of providing correct voltage levels.

I'm guessing that means the chip's maximum output is around 1.1V RMS, and its maximum input before ADC clipping is around 1.1V RMS. Your particular sound card may have additional components that amplify or attenuate the signals between the 8738 chip and the audio I/O connectors. Maybe you can examine the card and trace the circuitry.

Most sound cards can only handle input signals over a range of +/-2.5 volts. Although they may be able to tolerate somewhat larger signals, information about the exact limits is not generally available to the user and shouldn't be depended upon.

In this PDF they mention that the probe limits the input to the sound card to three volts max. I would suggest a three volt zener across the sound card inputs would limit the signal to +3V and -0.7V. Since you are interested in a digital signal anyway, any signal clipping by the zener will not be a problem.

of 1 to 10MOhm. In general sound cards have a much lower impedance, ranging from 600 Ohm to 47kOhm. One could use the microphone input for better sensitivity, but the noise floor is higher, and many cards output a voltage for microphone supply. If that input is used, a capacitor for blocking this voltage is necessary!
