The TS419IST is an integrated circuit (IC) power amplifier designed with cutting-edge audio technology that offers superior sound quality. It is a part of the range of high-performance ICs supported by Texas Instruments and is ideal for a wide range of consumer and professional applications. The TS419IST is a 2.2-Watt maximum power linear-amplifier that works with a dual-rail supply voltage (Vss and VCC) of ± 5 volts. What makes the TS419IST stand out is that it can deliver powerful and clear audio with minimum quiescent power while being able to handle maximum signal levels without distortion. It also offers three gain possibilities to tailor the sound quality according to the desired application.

The TS419IST is extremely versatile and can drive virtually any loudspeaker type and design, from tiny earbuds to 8-inch speaker drivers. Its bipolar class AB topology layout provides optimal output quality, thanks to its low harmonic distortion. This makes the TS419IST ideal for several audio applications, including portable audio players, car audio systems, and MP3 players. The amplifier can also be used for digital applications, such as digital-to-analog (DAC) controller chips, audio codecs, home theater systems, and more.

The TS419IST works with a low quiescent current of 5mA, making it a very efficient amplifier, with high power-saving capabilities. It also comes with two stand-by pins that can shut down the amplifier when not in use and make it even more energy efficient. Additionally, the TS419IST is equipped with a mute pin that easily can be triggered when a signal is not present.

The TS419IST also has a number of additional features that make it a great choice for audio applications. It is protected against any damage caused by output shorts, and has a temperature range of -40 degrees Celsius up to 110 degrees Celsius. Lastly, it has an acoustic corridor input pin, which allows for easy and precise gain adjustments.

Overall, the TS419IST is an advanced linear-amplifier audio IC that offers superior sound quality for a wide range of audio applications. Its low-power consumption, multiple functions and features make it an ideal choice for any audio application. Whether it is used in consumer applications, such as portable players, or professional applications, such as digital codecs, the TS419IST offers excellent performance and reliability.
