KBA2338 Datasheet (Kingbor Technology) - 3W F ilterless C lass-D Audio Power Amplifier

KBA2338, 3W F ilterless C lass-D Audio Power Amplifier

The kB2338A is a high efficiency, 3W mono class-D audio power amplifier.

A low noise, filterless PWM architecture eliminates the output filter, reducing external component count, system cost, and simplifying design.

Operating in a single 5V supply, kB2338A is capable of driving 4ȍ speaker load at a
