NJW1240V-TE1 Nisshinbo

NJW1240 5Vrms Ground Referenced 6-Channel Line Amplifier PACKAGE OUTLINE 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. NJW1240V FEATURES Operating Voltage +6 to +10V Operating Current I=15mA typ. DD + at V =8V, R =47k , No Signal L Maximum Output Voltage 5.0Vrms min. Low Distortion 0.0008% typ Low Output Noise -102dB typ. Output Coupling Capacitor-less External Synchronizing Divide-by-2 Pop Noise Suppression Circuit External Mute Gain Select +6dB/+8.3dB RF Immunity OpAmp tolerant to FR noise.
