I'm using a 8-bit DAC: (DAC5311IDCKR) to generate a 1.5V Amplitude sine wave with a 3.5VDC offset. I've put high-pass RC filter across it shown below to block DC so that it becomes AC.
I understand that the capacitor will act like a voltage source, and my SPICE simulator tells me that the cap's voltage becomes greater the source and (ideally) pass current back into the DAC. I'm concerned that this will either, damage the chip or not work at all because the chip doesn't allow currents in reverse.
- Is my concern valid?
- If so, when choosing a DAC what features should I look for on datasheets that tells me I can drive a load like this?
