TECHNICAL NOTE Speaker / Headphone Amplifier Series 5W+5W Stereo Speaker Amplifiers 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 5W×2 can be produced when VCC=12 V and RL=3Ω, and 2.8 W×2 when VCC=9V and RL=3Ω. The BA5406, which uses a 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. ●Product lineup Part No. Supply voltage [V] Power dissipation [W] Quiescent current [mA] Standby current[μA] Closed loop voltage gain [dB] Output noise voltage [mVrms] Total harmonic distortion [%] Ripple rejection [dB] Package BA5406 5～15 20 40 ― 46 0.6 0.3 ― SIP-M12 BA5417 6～15 15 22 0 45 0.3 0.1 55 HSIP15 Oct. 2005 ●Absolute maximum ratings (Ta=25°C) Parameter Symbol Supply voltage Vcc Power dissipation Pd Operating temperature Topr Storage temperature Tstg *1 When no signal *2 Back metal temperature 75°C *3 Ta=75°C (Using infinite heatsink) Limits BA5406 18 *1 20 *2 -20～+75 -30～+125 Unit BA5417 20 *1 15 *3 -20～+75 -55～+150 V W °C °C ●Operating range (Ta=25°C) Parameter Symbol Supply voltage VCC Limits BA5406 5.0～15.0 Unit BA5417 6.0～15.0 V ●Electrical characteristics (BA5406 : Unless otherwise noted, Ta=25°C, Vcc=12V) (BA5417 : Unless otherwise noted, Ta=25°C, Vcc=9V) Symbol BA5406 BA5417 Unit.

Numbers and data in entries are representative design values and are not guaranteed values of the items. 2. Although ROHM is confident that the example application circuit reflects the best possible recommendations, be sure to verify circuit characteristics for your particular application. Modification of constants for other externally connected circuits may cause variations in both static and transient characteristics for external components as well as this Rohm IC. Allow for sufficient margins when determining circuit constants. 3. Absolute maximum ratings Use of the IC in excess of absolute maximum ratings, such as the applied voltage or operating temperature range (Topr), may result in IC damage. Assumptions should not be made regarding the state of the IC (short mode or open mode) when such damage is suffered. A physical safety measure, such as a fuse, should be implemented when using the IC at times where the absolute maximum ratings may be exceeded. 4. GND potential Ensure a minimum GND pin potential in all operating conditions. Make sure that no pins are at a voltage below the GND at any time, regardless of whether it is a transient signal or not. 5. Thermal design Perform thermal design, in which there are adequate margins, by taking into account the permissible dissipation (Pd) in actual states of use. 6. Short circuit between terminals and erroneous mounting Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other components on the circuits, can damage the IC. 7. Operation in strong electromagnetic field Using the ICs in a strong electromagnetic field can cause operation malfunction. 2/8 ●Block diagram Fig.1 BA5406 T.S.D 30k 30k 30k 30k ST.BY VCC OUT1 BS1 POWERGND 10 11 12 13 PRE GND2 OUT2 9 14 15 PREGND2 BS2 8 PRE GND1 7 NF2 6 IN2 5 IN1 4 NF1 3 FILTER 2 45 FILTER STBY 1 (N.C.)
