3-channel 75Ω driver
BA7660FS
The BA7660FS is a 75Ω driver with a 6dB amplifier and three internal circuits, and provides 75Ω drive of composite
Y signals and C signals, as well as RGB signals. Each load is capable of driving two circuits, and a sag correction
function reduces the capacitance of the output coupling capacitor.
The input voltage is within a range of 0V to 1.5V, enabling direct connection of ordinary D / A converter output. An
internal power-saving circuit is also included which provides simultaneous muting on all three channels, and output
pin shorting protection.
