3-Chanels Differential Output Line Amplifier

Download Datasheet

  • Description

    The NJW1241 is a differential output 3-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 /single-end output 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.
