12V / 5W dual power amplifier

BA5406

The BA5406 is a dual-OTL monolithic power IC with two high-output, low-frequency power amplifiers. With a 12V power

supply, it has a rated output of 5W

2 into a 3

Ω load, and with a 9V power supply, it has a rated output of 2.8W

2

into a 3

Ω load.

The BA5406 has good low-voltage characteristics, and the “pop” sound when power is applied is small. It generates little

radio-band noise, and is ideal for use in stereo radio cassette players.

FApplications

Stereo radio cassette players, stereo component systems, and TVs.

FFeatures

1) Small “pop” noise.

2) Good low voltage characteristics. Begins operating

3) Good channel balance.

4) Good distortion characteristics

5) Easy-to-mount 12-pin SIP-M package that requires

little PCB space.

6) The ripple filter pin (pin 6) can be used for muting (by

setting it to ground potential).

7) Symmetrical pin assignments simplifies PCB art-

work.

8) Package has low thermal resistance to simplify

heatsink design.

9) Built-in treble phase compensation capacitors.

10) Low radio-band noise generated. Can be freely

positioned in the set.
