NJU72011

NJU72011 2Vrms Ground Referenced Stereo Line Amplifier with LPF s GENERAL DESCRIPTION The NJU72011 is an audio line Amplifier . It can swing 2Vrms (5.6V peak-to-peak) signal at 3.3V operating voltage. Ground-referenced outputs eliminate output coupling capacitor. The pop noise suppression circuit removes a pop noise at the power-on and power-off. It is suitable for audio line interface of audio equipment which does not have over 9V regulator. s PACKAGE OUTLINE NJU72011RB2 NJU72011V s APPLICATIONS q Audio applications requiring 2Vrms outputs s FEATURES q Operating Voltage q Operating Current q Output Coupling Capacitor-less q Pop Noise Suppression Circuit q LPF q C-MOS Technology q Package Outline +2.7 to +3.6V IDD=5mA typ. at V+=3.3V, RL=47kΩ, No Signal TVSP10, SSOP14 s BLOCK DIAGRAM V+ INL OUTL Mute Tr INR MUTE OUTR Bias Pop Noise Suppression Mute Tr Charge Pump V- GND CP CN Ver.1.2E –1– NJU72011 s PIN CONFIGURATION TVSP10 1 10 56 No. Symbol Function 1 INL Lch Input 2 OUTL Lch Output 3 V+ V+ Power Supply 4 CP Flying Capacitor Positive Terminal 5 CN Flying Capacitor Negative Terminal 6 V- V- Power Supply 7 MUTE Mute / Pop Noise Suppression 8 GND Ground 9 OUTR Rch Output 10 INR Rch Input SSOP14 1 7 14 No. Symbol 1 NC NC Function 2 INL Lch Input 3 OUTL Lch Output 4 V+ V+ Power Supply 5 CP Flying Capacitor Positive Terminal 6 CN Flying Capacitor Negative Terminal 7 NC NC 8 NC NC 8 9 V- V- Power Supply 10 MUTE Mute / Pop Noise Suppre...
