BA9756FS
The BA9756FS is LSIs that control CRT anode voltage in multi-scan monitors and similar devices, using
a chopper-type voltage control circuit. The internal sawtooth wave generator circuit uses automatic gain control
(AGC) to enable coverage of a wide range from 30kHz to over 150kHz. The BA9756FS is equipped with an internal
high-precision voltage source featuring an output voltage precision of ± 0.7%.
