Ver. 1.1E

5Vrms Ground Referenced 6-Channel Line Amplifier

GENERAL DESCRIPTION

The NJW1240 is a 6-channel audio line amplifier for High

Voltage Pre-out of Car AV system. It can swing

5Vrms(14.1V peak-to peak) singal at 8V opearating voltage

because of including the charge pump circuit.

Ground-referenced outputs eliminate output coupling

capacitor. The pop noise suppression circuit reduces a pop

noise at the power-on and power-off.
