STPA008 enriches your listening experience

STPA008 enriches your listening experience

The STPA008 is the latest automotive-grade class AB analog input power amplifier of the STPA family designed to enrich the car audio listening experience. It embeds 4 audio channels able to deliver a maximum power of 50 W each, it can drive loads as low as 2 W and operate from 6 to 18 V without popping or interruption. This makes the product compatible with start-stop and hybrid vehicles. An exciting sound quality level is guaranteed by its particular architecture built using ST's exclusive BCD6sA smart power technology, specifically designed for audio performance. The STPA008 helps ensure excellent immunity against interference coming from mobile devices (the so-called “GSM effect”), saving input filtering components (capacitors, inductors). Radio manufacturers can further save components and space on the board since all features are integrated and the STPA008 offers extreme robustness against misconnections.

The product is available in both Flexiwatt25 and Flexiwatt27 packages.
