NJW1230
1ch Video Amplifier &
2Vrms Ground Referenced Stereo Line Amplifier
Q GENERAL DESCRIPTION
The NJW1230 is an audio line Amplifier with 1ch video
amplifiier.
Audio line amplifier can swing 2Vrms (5.6V peak-to-peak)
signal at 3.3V operating voltage.
Ground-referenced outputs eliminate output coupling capacitor.
The pop noise suppression circuit removes a pop noise at the
power-on and power-off.
Video amplifier contained LPF circuit. Internal 75Ω driver is
easy to connect TV monitor directly.

Note)
When AC coupling and the video output connect two line of 150Ω ,connect the coupling capacitor after connecting the Vout pin
and Vsag pin. The recommended value is 470µF or more.

3. How to trace V+1(1pin), V+2(12pin), GND1(6pin), GND2(11pin)
V+1 and GND1 for audio block. V+2 and GND2 for video block. Audio block built in charge pump circuit. As a
result, clock noise of charge pump circuit on between V+1 and GND1. Video output is take a leaf from clock noise
at clock noise on between V+2 and GND2. Each terminal make a separation trace. Cut down common impedance of
between audio block and video block.
