The STA529Q is a linear amplifier designed for audio applications. It features a maximum output power of 120W into an 8 Ohm load and can be used to drive 4 - 8 Ohm loudspeakers with ease. The STA529Q has a low distortion up to 0.02%, with a low noise floor of -109 dBV and low output impedance of 0.013 Ohm. A bridge mode is also supported, making it a versatile amplifier for use in a variety of audio applications.

The STA529Q is designed for maximum efficiency, with a typi cal quiescent power consumption of 80W and a stand-by efficiency of 90%. Its operating voltage range is from 4.5V to 16V and can handle up to 40V total Bias voltage. The working principle of the STA529Q is based on the concept of linear power amplifier, which means it is able to provide a linear conversion of input signal to output without significant distortion of the original signal. The STA529Q uses Class AB operation, meaning it combines Class A and Class B operation to achieve a better performance in power output and efficiency.

The STA529Q also features integrated protection circuitry, which can detect faults such as over temperature, over voltage and DC offset, and then shut down the amplifier accordingly. Additionally, it has a pop- and click-reduction circuitry to reduce the unwanted noise when powering on or off.

The STA529Q is a versatile amplifier designed for audio applications, with a low distortion and low noise floor, an efficient power consumption and integrated protection circuitry. With its bridge mode feature it can easily drive 4-8 Ohm loudspeakers, allowing for a wide range of audio applications.
