TL071 Op-Amp Low-Noise IC Datasheet

Introduction

The TL071 Operational Amplifier IC is a low-noise, high-performance JFET-input op-amp widely used in audio, instrumentation, and signal processing applications. Designed with low input bias and offset currents, the TL071 offers excellent precision and stability in both single-supply and dual-supply circuits. Its combination of low noise density (18 nV/√Hz at 1 kHz) and low total harmonic distortion (THD) makes it one of the most popular operational amplifiers for high-fidelity audio preamplifiers, filters, and active equalizers.

One of the standout features of the TL071 op-amp IC is its high input impedance due to the JFET input stage, which minimizes loading effects on the signal source. With a high slew rate of 13 V/µs and a gain-bandwidth product of 3 MHz, the TL071 provides fast and accurate signal amplification, making it highly suitable for high-speed analog circuits. It operates across a wide supply voltage range from ±3V to ±18V (or single supply 6V to 36V), ensuring flexibility in both low-power and high-performance designs.
