Video Processing ICs

The LMH1983SQ/NOPB is a high-performance, low-distortion, differential input audio amplifier from Texas Instruments. This device is specifically designed for high-fidelity audio applications that require precise signal processing and minimal distortion.

Description:

The LMH1983SQ/NOPB is a fully differential input audio amplifier with a high input impedance and low output impedance. It is available in a small, thermally enhanced, 28-pin QFN package (LMH1983SQ) and a 28-pin plastic DIP package (LMH1983SQ/NOPB). The device features a high slew rate and low harmonic distortion, making it suitable for a wide range of audio applications.

Features:

1. Differential input stage: Provides excellent common-mode rejection and improved noise immunity.
2. High slew rate: Up to 13 V/µs, ensuring fast response and minimal distortion in high-frequency applications.
3. Low harmonic distortion: -92 dBc at 1 kHz, 0.5 W output, and 10 kHz input, resulting in high-quality audio performance.
4. Wide supply voltage range: Operates from a single supply of 2.7 V to 5.5 V, making it suitable for various power supply configurations.
5. Low output impedance: Facilitates easy load driving and integration with other audio components.
6. Thermal protection: Includes over-temperature protection to ensure safe operation and prevent damage in case of excessive heat.
7. Small package options: Available in a 28-pin QFN package for space-constrained applications and a 28-pin plastic DIP package for easy prototyping and through-hole applications.

Applications:

1. Professional audio equipment: Mixing consoles, audio processors, and preamplifiers.
2. High-fidelity audio systems: Home theater systems, high-end audio receivers, and soundbars.
3. Portable audio devices: High-quality headphones, portable audio players, and Bluetooth speakers.
4. Medical equipment: Audio signal processing in hearing aids and other medical diagnostic equipment.
5. Industrial audio systems: Public address systems, intercoms, and alarm systems.
6. Automotive audio systems: In-vehicle entertainment systems, sound processing, and active noise control.

The LMH1983SQ/NOPB is a versatile and high-performance audio amplifier suitable for a wide range of applications that demand precise signal processing and minimal distortion. Its differential input stage, high slew rate, and low harmonic distortion make it an excellent choice for professional and high-fidelity audio systems.
