BA5406 ROHM

Class-AB Speaker Amplifiers 5W+5W Stereo Speaker Amplifiers No.13077EDT02 BA5406,BA5417 Description The BA5406/BA5417 is a dual OTL monolithic power IC with two built-in, high output speaker amplifier circuits. High output of 5W2 can be produced when V =12 V and R =3, and 2.8 W2 when V =9V and R =3. The BA5406, which uses a CC L CC L high allowable power dissipation package, has a simple heatsink design. The BA5417 not only exceeds basic characteristics, but also has a built-in soft clip circuit, thermal shutdown and standby circuits. Features BA5406 1) Good low voltage characteristics (Operation from Vcc=5 V) 2) Ripple filter (6pin) also can be used as muting pin (Make 6pin GND potential) 3) Small thermal resistance package and simple heatsink design BA5417 1) Small pop noise when standby switches ON/OFF 2) Built-in circuit to prevent ripple addition when motor starts 3) Built-in thermal shutdown circuit 4) Built-in standby switch circuit 5) Built-in soft clip circuit Applications Stereo radio cassette players, mini-audio systems, LCD TVs, etc. Line up matrix Part No. BA5406 BA5417 Units Supply voltage 5 ~ 15 6 ~ 15 V Power dissipation 20 15 W Quiescent current 40 22 mA Standby current 0 A Closed loop voltage gain 46 45 dB Output noise voltage 0.6 0.3 mVrms Total harmonic distortion 0.3 0.1 % Ripple rejection 55 dB Package SIP-M12 HSIP15 www.rohm.com 2013.11 - Rev.D 1/10 2011 ROHM Co., Ltd.
