Introduction to the INA134UA/2K5

The INA134UA/2K5 is a high-performance, low-noise, single-stage differential-to-differential amplifier manufactured by Texas Instruments. This linear audio amplifier is best known for its wide gain range and low operating voltage of only 5.0V, making it a perfect choice for almost any linear audio application.

Applications

The INA134UA/2K5 can be used in a variety of audio and dynamic signal processing applications where a wide gain range and low voltage operation are desired. Common applications include sound pressure level measurement, line-level audio amplification, microphone amplifiers, as well as dynamic operation amplifiers (op-amps).

Features

The INA134UA/2K5 has a wide gain range of 0.5-104dB and low operating voltage of only 5V. It is capable of driving a maximum of 4mA of output current and features low distortion (THD+N) of 0.0004%. This linear audio amplifier also features a low thermal noise of 0.75nV/rtHz and very low supply current of only 1.5mA. The amplifier is packaged in a small 8-pin SOIC package, making it easy to use and integrate into a variety of applications.

Working Principle

The INA134UA/2K5 uses a single-stage differential input amplifier to achieve its higher gain range and lower operating voltage. This type of amplifier utilizes two input pins to measure the voltage of a single input signal. The difference between the two inputs is then amplified, allowing the amplifier to produce higher gains while maintaining its lower operating voltage.Due to its low voltage and high gain range, the INA134UA/2K5 is capable of amplifying signals successfully with a small amount of power. In addition, the low noise and low distortion characteristics allow this amplifier to produce a high-quality audio signal with minimal amount of interference.

Conclusion

The INA134UA/2K5 is a versatile, low-voltage audio amplifier ideal for a variety of linear audio applications. Its wide gain range, low operating voltage, and low distortion characteristics make it an ideal choice for sound level measurement, sound production, and other audio processes. With its small form factor and easy integration capabilities, this linear audio amplifier is a great choice for almost any audio project.
