Rohm BA5406 5w5w stereo speaker amplifier Datasheet

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.

●Cautions on use
1. 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.
