DESCRIPTION

The STA5150 is a fully integrated power module designed to implement a BASH? amplifier when used in conjunction with STABP01 digital processor.

Notice that normally only one Digital Converter is needed to supply a stereo or multi-channel amplifier system, therefore most of the functions implemented in the circuit have summing outputs

The signal circuits are biased by fixed negative and positive voltages referred to Ground. Instead the final stag es of the output amplifiers are supplied by two external voltages that are following the audio signal . In this way the headroom for the output transistors is kept at minimum level to obtain a high efficiency power amplifier.
