Voltage Controlled Panner
An interesting circuit that is built with the OVCE building block
is a voltage controlled panner. Figure 48 shows the feedback
connection for the circuit. Notice that the average of both out-
puts is fed back to the input. Thus, the average must be equal
to the input voltage. When the control voltage is set for gain at
V
On the other hand, when V
The result is that the control voltage causes the input to “pan”
from one output to the other. The following expressions show
how this circuit works mathematically:
where K varies between 0 and 1 as the control voltage is
changed from full attenuation to full gain respectively. When
V
required for best performance. Pin 9 should be grounded. This
is possible because the feedback is constant and the adaptive
network is not needed. The VCP is the only application shown
in this data sheet where Pin 9 is grounded.
