The INA163UA is an integrated circuit (IC) component manufactured by Texas Instruments. It is a high-performance differential amplifier that is primarily designed for professional audio applications. The IC provides excellent common-mode rejection ratio (CMRR), low distortion, and low noise characteristics, making it suitable for high-fidelity audio systems.
One of the key features of the INA163UA is its ability to amplify a differential input signal while rejecting any common-mode noise or interference. It achieves this through its high CMRR of typically 94 dB, ensuring a clear and noise-free output. The IC also offers a wide input voltage range, enabling the amplification of small input signals without significant distortion.
Another notable feature of the INA163UA is its low distortion performance, with a total harmonic distortion (THD) of typically 0.0005% at 1 kHz. This ensures that the amplified audio signal maintains its original quality and fidelity. Additionally, the IC has a low input-referred noise of 2
