75Ω driver with Y / C MIX circuit
BA7664FV
The BA7664FV is a 75Ω driver with a 6dB amplifier and a Y / C MIX circuit. The 75Ω driver is capable of driving a
load sufficient for two circuits, as well as being equipped with a sag correction function which reduces the capaci-
tance of the output coupling capacitor. The IC comes in the compact 8-pin SSOP-B package. The composite Y sig-
nal input pin is sync chip clamped input, while the chrominance input pin is bias input. An internal power-saving cir-
cuit is also included which provides an output muting function and output pin shorting protection.
