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.
