NJW1240
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.
