actually changes, is different depending on whether the voltage is increased or decreased as a result of the
hysteresis about each trip point. The gaps in Table 1 and Table 2 can also be thought of as indeterminate states
where the gain could be in the next higher gain step or the lower gain step depending on the direction the
voltage is changing. If using a DAC to control the volume, set the voltage in the middle of each range to ensure
that the desired gain is achieved.
A pictorial representation of the volume control can be found in Figure 34. The graph focuses on three gain steps
with the trip points defined in Table 1 for BTL gain. The dotted line represents the hysteresis about each gain
step.
