1.25 W Class-AB Audio Power Amplifier with RF Noise Suppression

The AW8090A is a 1.25W Class-AB audio power amplifier with RF Noise Suppression (RNS) and Thermal AGC function. The RNS function and High PSRR suppresses the RF TDD noise effectively in GSM application. The thermal AGC function, which adjusts the system gain automatically when the junction temperature reaches the thermal regulation threshold, prevents the device from over- heating and working Intermittently due to the simple thermal shutdown in the traditional Class-AB amplifiers. The AW8090A features unique timing control circuit, that comprehensively suppresses pop-click noise, eliminates audible transients on shutdown, wake-up, and power-up/down. The AW8090A is capable of delivering 1.25 W of continuous average power to an 8Ω BTL load with less than 1% distortion from a 5.0V power supply.
