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 3Ω load, and with a 9V power supply, it has a rated output of 2.8W  2
into a 3Ω 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.

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

Features

1) Small “pop” noise.

2) Good low voltage characteristics. Begins operating
V

CC = 5V (Typ.).

3) Good channel balance.

4) Good distortion characteristics
(THD = 0.3% when P

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).

O = 0.5W).

7) Symmetrical pin assignments simplifies PCB art­work.

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.
