The STA51813TR is a two chip audio linear amplifier solution for automotive and industrial applications. It has been designed to combine ease of use with robust performance in extreme temperature ranges. Its low power consumption and high efficiency allow for increased power for up to 7.5 W output, while maintaining a low quiescent current. The STA51813TR is ideal for automotive infotainment, radio applications, headsets and even audio playback in smart phones and tablets.

The STA51813TR features a low-power input stage based on a linear-amplifier integrated circuit (LIC). This input stage is designed to provide the highest achievable sound quality with optimal power efficiency. The integrated dual channel, partially differential LIC offers lower noise, better distortion performance and higher efficient operation compared to its predecessor, the LM386. Additionally, the STA51813TR features direct connection to speakers enabling simple integration into automotive applications.

The STA51813TR offers a high output power with an optimized power management algorithm. Its built-in advanced protection circuit makes it suitable for use in harsh automotive environments. Its high power efficiency, high current limit and low power consumption offer increased power for portable and automotive audio applications. The input stages of the STA51813TR support up to 8.5V from the supply power, allowing flexibility when using alternative power sources. Additionally, it supports both single-ended and differential input signals from almost any audio source.

The dynamic frequency response of the STA51813TR is also optimized for automotive and industrial applications. It has low harmonic distortion and provides high power efficiency for increased power at reduced levels of quiescent current. The STA51813TR utilizes peak current control technology to ensure optimal power efficiency and a high output power-supply rejection ratio (PSRR) to reduce electrical noise and cross-talk. The built-in thermal protection circuit allows the STA51813TR to operate in even the most extreme temperature ranges.

The STA51813TR is designed for robust and reliable performance in even the most demanding audio applications. Its high power efficiency, high current limit and low power consumption make it ideal for automotive and industrial audio applications. It can also be used in portable devices such as smart phones, tablets and audio-enabled headsets. Its built-in protection circuit ensures reliable performance in a variety of environmental conditions.
