Product Details

Description



Features:

• Wide operating supply voltage range (VCCop): 5.5 to 22 V (Certain conditions may apply.)
• High ripple rejection ratio: 60 dB (typical)
• Power: 16 W * 2 (VCC = 15 V/6), 13 W * 2 (VCC = 12 V/4), 6.5 W * 2 (VCC = 9 V/4)
• Built-in signal muting circuit (AC muting) reduces the number of external components and provides muting with minimal switching noise.
• Startup circuit with a start time of 0.6 to 0.7 seconds. The LA4663 provides distortion-free startup, since output is only generated after the supply voltage reaches the midpoint at power on.


Application

Radio/cassette players with built-in CD/MD players, microcomponent stereo systems, active speakers, electronic musical instruments, and other audio devices.
