PAL013A audio amplifier


An AB class audio power amplifier is a type of amplifier that combines the characteristics of Class A and Class B amplifiers. It is designed to provide improved efficiency compared to Class A amplifiers while maintaining good audio quality and reduced distortion compared to Class B amplifiers.

In an AB class amplifier, the input audio signal is split into two parts: a positive half-cycle and a negative half-cycle. Each half-cycle is amplified by a separate set of transistors (one for the positive half and another for the negative half) working in a push-pull configuration.

The PAL013A is an AB class audio power amplifier, packaged in Flexiwatt 25 and designed for high end car radio applications. Based on a fully complementary PNP/NPN configuration, the PAL013A allows a rail to rail output voltage swing with no need of bootstrap capacitors. The extremely reduced boundary components count allows very compact sets.

Pioneer Audio output, compatible with PAL011A / PAL012A without presenting the famous “Error of Amplifier “in the car stereo or getting solved without taking into account pin 1 and 27 to the board, 12V power supply.
