NJW1241 - 3-Chanels Differential Output Line Amplifier

Description

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.

NJW1241 3-Chanels Differential Output Line Amplifier „ GENERAL 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.
