APPLICATION CIRCUIT 2 (Two-line driving circuit)

(Note)

1. Put a bypass capacitor of 0.1µF near a V+ pin (V+1 to V+4).

2. Shorten the feedback loop of an output coupling capacitor and the SAG correction capacitor of the video signal

output and put a 75Ω series resistance near IC pin.

3. Two-line driving circuit

This circuit drives two-line of 150Ω. However, it may cause to lose synchronization by an input signal of large

APL change (100% white signals more than 1Vp-p). Confirm the large APL change waveform (100% white

signals more than 1Vp-p) and evaluate sufficiently.
