The Arduino expects 5V p-p, but AD9833 outputs only 0.6V p-p. How to get full-scale signal? Must we amplify with gain of about 8?
Also, Arduino input expects 0V to 5V -- is the AD9833 analog sine output bipolar, or single-sided? Must we convert?
Is op amp summing amp the preferred interface?
Using an off-the-shelf AD9833 module.
