3channel 75 driver
BA7666FS
The BA7666FS is 3channel 75 driver with 6dB amplifier and sag compensator, and available for composite Video, composite Y and so on. This driver can have two loads (75 ) and package is small (SSOPA16PIN). This input is sync-tip-clamp for all 3channnel. This has 3channel mute and power save circuits (each channel) operated for making output under 0.2v.
!Features 1) Sync-tip-clamp input 2) Low power consumption (Typ.117mW) 3) Built-in output mute circuit 4) Built-in power save circuit 5) Built-in output protection circuit 6) Can make output coupling capacitor smaller by the built-in sag correction circuit 7) Can drive two circuits by one output 8) Small package of SSOP-A16 pin
