STMicroelectronics' STPA008 MOSFET four-bridge power amplifier is hailed as a breakthrough Class AB audio power amplifier designed for high-power automotive radio systems. The fully complementary P-channel / N-channel output structure allows rail-to-rail output voltage swing. STPA008 combines high output current with minimal saturation loss. This sets a new power benchmark for unparalleled distortion performance in the vehicle radio field.
The STPA008 can operate at voltages as low as 6V, making the IC compliant with the latest OEM low-voltage operating specifications (known as "start-stop" battery profiles during engine shutdown). The company says this helps automakers reduce overall emissions and contribute to environmental protection.
