Si3232
4.3. DC Feed Characteristics
The Si3232 offers programmable constant voltage and
constant current operating regions as illustrated in
Figure 7 and Figure 8. The constant voltage region is
defined by the open-circuit voltage, V
programmable from 0 to 63.3 V in 1 V steps. The
constant current region is defined by the loop current
limit, I
0.87 mA steps. The Si3232 exhibits a characteristic dc
impedance of 320 Ω during Active mode.

lead in reverse polarity) for carrying audio signals. A
similar programmable voltage, V
offset between the most negative terminal and the
battery supply rail for carrying audio signals. (See
Figure 7.) The user-supplied battery voltage must have
sufficient amplitude under all operating states to ensure
sufficient headroom. The Si3200 may be powered by a
lower secondary battery supply, V
