STPA001H

Overview

The STPA001H is a Class-AB audio power amplifier utilizing MOSFET technology, designed for high-power automotive radio applications. It features a fully complementary P-Channel/N-Channel output structure enabling rail-to-rail voltage swing. The device operates on a single supply voltage ranging from 6V to 28V, with typical voltages of 9V, 12V, 15V, 18V, and 24V. It delivers up to 75W per channel into a 2Ω load and 48W per channel into a 4Ω load. Key electrical parameters include a maximum quiescent current of 300mA at 14.4V, a maximum operating temperature of 150°C, and a THDN of 0.01% at 4W into 4Ω.
