Figure 3a.
With no audio input signal applied, the AudioA/B
inputs are biased at the mid-point of the triangular
wave, and the duty cycle at the output of the
comparatorsisnominally50%. As theAudioA/Bsignal
ascends towards the peak level, the crossing points
with the (higher frequency) triangular wave also
ascend. The comparator monitoring these signals
exhibits a corresponding increase in output duty cycle.
Similarly, as the AudioA/B signal descends, the duty
cycleiscorrespondinglyreduced. Thustheaudioinput
Pulse Width Modulates the comparator outputs. This
principle is illustrated in Figures 3a, b, c and d. The
comparator outputs are buffered and used to drive the
OutAandOutBoutputs.Theseinturndrivethespeaker
load(withtheaudioinformationcontainedinthePWM
signal) via the off chip output bridge and single stage
L-C filter network.
The ramp amplitude is approximately 1V. The AudioA,
AudioB, TriangleA and TriangleB inputs are internally
biased to a DC voltage of approximately VCC/5. The
mid - point DC level of the OscA and OscB triangular
outputs is around 2V. The triangular wave at the Cosc
pin traverses between about 2.7Vand 3.8V and the dist
pin exhibits a roughly square wave from about 1.4V to
2V. (The above voltages may vary in practice and are
included for guidance only).
