Texas Instruments TL074ACN Quad Low-Noise JFET Op-Amp, DIP-14

The Texas Instruments TL074ACN is a high-performance, low-noise, JFET-input operational amplifier integrated circuit. Designed as part of a versatile and widely selected family, it incorporates well-matched, high-voltage JFET and bipolar transistors on a monolithic chip. This design delivers excellent electrical characteristics, including high slew rates and remarkably low input bias and offset currents, making it a superb choice for precision audio and instrumentation applications.

A key benefit of this quad op-amp is its very low harmonic distortion and noise floor, which renders the TL07x series ideally suited for high-fidelity audio preamplifiers and other sensitive signal conditioning circuits. The device features internal frequency compensation for stability, latch-up-free operation, and output short-circuit protection for enhanced robustness in real-world designs.

Key Features & Specifications

• JFET Input Stage: Provides an exceptionally high input impedance, minimising loading on signal sources.
• Low Noise & Distortion: Typical total harmonic distortion of just 0.003% ensures clean signal amplification.
• High Slew Rate: A 13 V/µs slew rate allows for fast signal response, suitable for audio and pulse applications.
• Wide Supply Range: Operates from a single 7V to 36V supply or dual ±3.5V to ±18V supplies, offering great design flexibility.
• Robust Design: Features include output short-circuit protection and a wide common-mode and differential voltage range.

Applications

This general-purpose op-amp is perfect for a multitude of electronic projects and professional equipment, including motor drive control circuits, precision test and measurement instrumentation, active filters, and summing amplifiers. Its through-hole DIP package makes it easy to prototype with on breadboards or to install permanently on printed circuit boards.
