STMicroelectronics TL084AC - Quad Low-Noise JFET-Input Operational Amplifiers

The TL084AC from STMicroelectronics is a high-speed integrated circuit consisting of four independent, high-gain, internally compensated, low-noise JFET-input operational amplifiers. This device is designed to offer a wide range of features making it suitable for a plethora of applications, ranging from audio and signal conditioning to active filters and voltage amplification.

The JFET input stage ensures low input bias and offset currents, which is particularly beneficial for high-impedance sensor amplification and precise long-term integration. With a typical low input noise voltage of 15 nV/√Hz, the TL084AC is an excellent choice for audio pre-amplification and other applications where noise performance is critical.

Each amplifier in the TL084AC quad op-amp features a high slew rate of 13 V/µs, contributing to its ability to handle fast signal transitions and high-frequency applications. The device operates over a wide range of power supply voltages, from ±3V to ±18V, providing designers with flexibility in various circuit configurations.

The TL084AC also boasts a large output voltage swing, which gets close to the power supply rails, thus maximizing the dynamic range in battery-powered and single-supply operations. This makes it a versatile choice for portable and low-voltage applications.

With its wide common-mode and differential voltage ranges, the TL084AC ensures reliable operation even under demanding conditions, while its low harmonic distortion and low noise make it a suitable op-amp for high-fidelity audio applications. The device also features latch-up-free operation, which enhances its robustness and reliability in electronic circuits.

Available in various packages, including the compact SO-14 and the standard DIP-14, the TL084AC can be easily integrated into both space-constrained applications and general-purpose designs. Its combination of performance, versatility, and reliability makes the TL084AC from STMicroelectronics a go-to choice for engineers and designers looking for a quad operational amplifier that can meet a wide array of design requirements.
