ST's complete family of “intelligent” analog automotive power amplifiers
ST offers a complete range of intelligent analog power amplifiers for automotive audio systems.
What makes these power amplifiers "intelligent" is their reliable diagnostics array that detects the status of each speaker and can identify any failure or speaker disconnection. Two- or four-channel versions with different power levels and features, like the automatic offset control, are available. The new generation has very high efficiency (class SB, class SB-I), consuming less than a standard class AB, a valid alternative to class D power amplifiers. Furthermore, ST is the only company offering an automotive analog power amplifier with a digital input. All our amplifiers are compatible with hybrid and start-stop engines, working with a battery of just 6V.
