I want to generate a sine wave of frequencies 10KHz and 250KHz from DAC8822.
For a brief reading of the datasheet, I've needed some clarifications and hoping you guys can solve it.
The DAC is communication with a 3.3V logic controller. The minimum logic input voltage when driven from a +5V is 2.4V.
1). Which are the logic output pins?.
2). What are 2 quadrant and 4 quadrant modes of operation?.
3). I want a +/-14V bipolar sine wave from the DAC, so what should be the value of Vref?.
4).In the table below, if I understand it correctly,
The output of the DAC would be only 0 to 5V for VDD=5V. Or am I wrong?.
5). The output of the DAC is fed to a 4th order LPF,
