Ordering number : ENN5905A Monolithic Linear IC LA4663 Two-Channel 16-W BTL General-Purpose Audio Power Amplifier (The startup time can be modified in end products by Overview using this circuit in conjunction with the muting circuit The LA4663 is a BTL 2-channel power amplifier IC that described above.) was developed for ease of use in general audio Full complement of built-in protection circuits applications. In addition to providing improvements in a (protection from shorting to ground, shorting to V , CC wide range of electrical characteristics, the LA4663 aims load shorting, and overheating) for improved listenability and an excellent cost- High audio quality, minimal impulse noise performance ratio. Applications Package Dimensions Radio/cassette players with built-in CD/MD players, unit: mm microcomponent stereo systems, active speakers, 3113A-SIP14HZ electronic musical instruments, and other audio devices. LA4663 4.0 27.0 Features 20.0 Wide operating supply voltage range (V op): 5.5 to CC 22 V (Certain conditions may apply.) High ripple rejection ratio: 60 dB (typical) Power: 16 W 2 (V = 15 V/6), CC 13 W 2 (V = 12 V/4), 6.5 W 2 (V = 9 V/4) CC CC Built-in signal muting circuit (AC muting) reduces the number of external components and provides muting 1 14 with minimal switching noise. 1.94 0.5 0.4 1.6 3.56 Startup circuit with a start time of 0.6 to 0.7 seconds. 2.2 The LA4663 provides distortion-free startup, since output is only generated after the supply voltage reaches 1.78 3.56 SANYO: SIP14HZ the midpoint at power on.
