3-channel 75

Ω driver with Y / C MIX

BA7665FS

The BA7665FS has three 75

Ω driver circuits with 6dB amplifiers, and includes a Y / C MIX circuit. The IC can pro-

vide a 75

Ω 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.

Digital AV equipment, DVD and DVC players

1) Y / C MIX circuit.

2) Low power consumption (typ. 130mW).

3) Output mute circuit.

4) Power save circuit.

5) Output protection circuit.

6) Sag compensation circuit allows small output cou-

pling capacitors.

7) Two-circuit drive possible for loads.

8) Compact SSOP-A 16-pin package.
