3-channel 75W driver with Y / C MIX
BA7665FS
The BA7665FS has three 75W driver circuits with 6dB amplifiers, and includes a Y / C MIX circuit. The IC can pro-
vide a 75W drive with a composite Y signal, C signal, or a Y / C MIX signal. Dual-circuit drive capacity for each load
is provided, and a sag compensation function is provided to allow use of smaller coupling capacitors.
The composite Y signal input is a sync-tip clamp input, and the chroma input is a biased input.
The three channels can be simultaneously muted, or the chroma signal only (in the case of C / Y output, only Y is
output), and output short circuit protection and power save circuits are also provided.
