14.3 PWM DAC Mode Options
The PWM DAC generator has three modes, Single-pin
mode, Two-pin two-ended mode and Two-pin push pull
14.3.1 Single-Pin Mode (7-bit Accuracy)
Single-pin mode is designed for use with a single-transistor
amplifier. It has 7 bits of resolution. The duty cycle of the
PSGO is proportional to the output value. If the output value
is 0, the duty cycle is 50%. As the output value increases
from 0 to 63, the duty cycle goes from being high 50% of

the time up to 100% high. As the value goes from 0 to -64,
the duty cycle decreases from 50% high to 0%. PSGOB is
inverse of PSGO’ s waveform. Figure 13-3 shows the PSGO
waveforms.
