BA5406 Stereo Speaker Amplifier ic chip / linear integrated circuits

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 V_CC=12 V and R_L=3Ω, and 2.8 W×2 when V_CC=9V and R_L=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.

Absolute maximum ratings (Ta=25°C)

*1 When no signal

*2 Back metal temperature 75°C

*3 Ta=75°C (Using infinite heatsink)
