NJW1240

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. s PACKAGE OUTLINE „ FEATURES q Operating Voltage +6 to +10V q Operating Current q Maximum Output Voltage IDD=15mA typ. at V+=8V, RL=47kΩ, No Signal 5.0Vrms min. q Low Distortion 0.0008% typ q Low Output Noise -102dB typ. q Output Coupling Capacitor-less q External Synchronizing Divide-by-2 q Pop Noise Suppression Circuit q External Mute q Gain Select +6dB/+8.3dB q RF Immunity OpAmp tolerant to FR noise.
