It is available in two different packages, Flexiwatt25 and Flexiwatt27. It embeds four independent amplifiers working in class AB, a standby and a mute pin, an offset detector and, only for the Flexiwatt27 package, 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. STPA008 can drive 2 ohm loads and has a very high immunity to disturbs without need of external components or compensation. It is protected against any kind of short or open circuit, over-voltage and over-temperature. 1.1 Block diagram and application circuit Figure 1.
