ST公司汽车音响功放芯片选型指南
汽车AB类音频功放ST offers a complete class-AB product portfolio. As well as standard class-AB power amplifiers, ST proposes audio amplifiers in class SB (Single-ended Bridge) and SB-I (SB improved). As a result of their high efficiency, these classes reduce power dissipation by up to 50% compared to standard class AB, simplifying thermal management in current power sets. Moreover, ST has introduced a digital input to offer a clean sound, immune to external interferences. Amplifiers can now be directly connected to the DSP output without any signal conversion. ST also proposes amplifiers that are compatible with start-stop and hybrid engines.
ST's class-AB automotive audio amps offer:
[*]Clean, powerful audio
[*]A wide portfolio, single-channel devices to powerful quad-channel single-chip devices
[*]Robust designs with integrated protection against short circuits, ESD, load dumping, over-temperature
[*]Ability to drive very low impedance speakers (as low as 1 ohm)
[*]Products compliant with new stop-start engine and hybrid engine standards
[*]Optional I²C interface and diagnostics
[*]Optional digital input
[*]Optional augmented efficiency
