Overview

STPA008ZS is a complementary quad audio power amplifier. It embeds four independent

amplifiers working in class AB, a standby and a mute pin, an offset detector and a clipping

detector and diagnostics output. The amplifier is fully operational down to a battery voltage

of 6 V, without producing pop noise and continuing to play during battery transitions.

STPA008ZS can drive 2 ohm loads and it has a very high immunity to disturb without need

of external components or compensation. It is protected against any kind of short or open

circuit, over-voltage and over-temperature.
