3-channel 75Ωdriver
BA7660FS
The BA7660FS is a 75Ωdriver with a 6dB amplifier and three internal circuits, and provides 75Ωdrive 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.
Applications
•
DVDs, set top boxes and other digital video devices
Features
•
1) Can be coupled directly to D / A converter output.
2) Operates at a low power consumption (115mW typ.).
3) Internal output muting circuit.
4) Internal power-saving circuit.
5) Internal output protection circuit.
6) An internal sag correction function makes it possible
to reduce the capacitance of the output coupling
capacitor.
7) Each load is capable of driving two circuits.
8) The compact 16-pin SSOP-A package is used.
