**OP275GSZ-REEL7: High-Performance Audio Operational Amplifier for Precision Applications**

In the realm of high-fidelity audio and precision signal processing, the choice of operational amplifier is critical. The **OP275GSZ-REEL7** stands out as a premier component engineered specifically for applications where exceptional audio quality and accuracy are non-negotiable. This op-amp combines the coveted sonic characteristics of classic bipolar and JFET-input amplifiers, delivering a unique blend of low noise, high slew rate, and minimal distortion that defines high-performance audio pathways.

At the heart of its design is a proprietary linear IC technology that integrates both bipolar and JFET transistors on a single chip. The bipolar inputs ensure **exceptionally low voltage noise density**, crucial for amplifying minute signals without adding hiss or degradation. Simultaneously, the JFET-input stage provides **ultra-low bias current**, making it ideal for applications involving high-impedance sources like professional audio mixers, precision filters, and high-quality digital-to-analog converter (DAC) output buffers.

A key performance metric for any audio op-amp is Total Harmonic Distortion plus Noise (THD+N). The OP275GSZ-REEL7 excels here, boasting an impressively **low THD+N of 0.0006% at 1 kHz**, which preserves the integrity of the original signal and ensures that the amplified output is a pristine reproduction of the input. This is further complemented by a **high slew rate of 22 V/μs**, enabling the amplifier to accurately track fast-moving audio signals without introducing transient intermodulation distortion—a common pitfall in inferior designs.

The device is also designed for robust operation across a wide range of conditions. It supports a **wide supply voltage range from ±5V to ±22V**, offering designers flexibility in both dual and single-supply configurations. Its ability to drive challenging loads, such as low-impedance headphones or long cables, while maintaining stability, makes it a versatile choice for preamplifiers, active crossovers, and professional audio equipment.

**ICGOOODFIND**: The OP275GSZ-REEL7 is a top-tier audio operational amplifier that masterfully balances technical excellence with sonic purity. Its hybrid architecture sets a high benchmark for precision audio amplification, making it an indispensable component for designers who refuse to compromise on performance and fidelity.
