LOW FREQUENCY SINE WAVE OSCILLATOR
The DS-11802 can be used to create a low frequency sine wave
oscillator with very low distortion (see FIGURE 10). The output
amplitude is determined by the amplitude of the dc reference
input and the gain control pin configuration. When using a 16-bit
counter and a square wave of 65,536 Hz (2N, where N = 16 bit
resolution) the output will be at 1 Hz.

Decoupling capacitors are recommended on the +Vs and -Vs.
supplies. A 1
F tantalum capacitor in parallel with a 0.01 F
ceramic capacitor should be mounted as close to the supply as
possible.
