BA7665FS

Multimedia ICs 3-channel 75Ω driver with Y / C MIX BA7665FS The BA7665FS has three 75Ω driver circuits with 6dB amplifiers, and includes a Y / C MIX circuit. The IC can provide a 75Ω 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. Applications Digital AV equipment, DVD and DVC players Features 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 coupling capacitors. 7) Two-circuit drive possible for loads. 8) Compact SSOP-A 16-pin package.
