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.

•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.
