The STA505 is a highly efficient monolithic power amplifier that combines a high performance amplifier with a high operation power, and is perfect for applications like consumer audio systems and automotive audio, which need a low power amplifier to achieve cost efficiency and reduce power consumption while at the same time delivering high-quality audio reproduction. Offering superior performance over existing conventional transistors, the STA505 offers designers an easy-to-use power amplifier that can provide very high-efficiency audio reproduction with small form factor and low cost.

The STA505 is based on linear design and utilizes a high speed implementation of differential input drivers, class-d outputs and high frequency compensation to achieve optimal performance. This allows the STA505 to operate at high speeds with minimal power consumption while at the same time providing excellent audio performance. The high frequency compensation and class-d output help reduce power consumption and provide high sensitivity and high efficient audio performance.

The STA505 includes an integrated charge pump and thermal protection circuitry, making it suitable for use in audio amplifiers for consumer and automotive usage. The charge pump helps reduce power consumption and allow the amplifier to operate in two modes: low power mode, which saves power when the audio signal is low, and high power mode, which increases efficiency at higher audio signals.

The STA505 features a differential input stage with low voltage common mode, ensuring low distortion and superior signal-to-noise ratio (SNR). It also utilizes a high performance output stage that provides excellent audio fidelity and high power efficiency. The output stage is optimized for low output impedance and low harmonic distortions while delivering high power.

The STA505 also has an integrated high-frequency boost feature which helps reduce the effect of audio frequency attenuation and increase sound clarity. The high frequency boost feature also helps reduce distortion at high frequencies. The STA505 also features low noise, low distortion, low output offset and low quiescent current, making it suitable for use in professional audio systems.

The STA505 is capable of powering up to 4 speakers with a single stage and 8 speakers with two stages. It is rated for up to 80 watts per channel with low harmonic distortion. Additionally, it has a low power consumption and low temperature operating range, making it suitable for applications requiring extended battery life or thermal efficiency.

In summary, the STA505 is a highly efficient, monolithic power amplifier that combines a high performance amplifier with a high operation power. It provides superior performance over existing conventional transistors, and is ideal for applications like consumer audio systems and automotive audio, which need a low power amplifier to achieve cost efficiency and reduce power consumption while at the same time delivering high-quality audio reproduction.
