Features
1) Reference voltage precision is
1%.
2) Output stages are based on the push-pull method
(resembling the totem-pole method), and ON / OFF
currents can be set independently.
3) Triangular waves can be externally synchronized.
4) Pins allow ON / OFF control of channel 3 only, or all
channels at once.
