Internal primary filter is composed of sourcing/sinking current source of 25uA and forward/reverse controlled switches.
It converts "FWD/REV" digital signals to analog signal as shown Figure. 2.
Figure 3. Operartion waveforms of BTL Driver (CH1, CH2 and CH3)
If the forward input signal is high level (avobe 2.4V) and reverse input signal is low level (under 0.5V), then the forward
current source switch S1and reverse current source switch S2 become turn-on and turn-off, respectively.
This causes the internal capacitor, C1, to be charged with sourcing current source of 25uA and consequently the voltage of
the filter output, V
A
, increases with the internal time constant of 2.5usec.
The time constant is
