TL072CDT Low-Noise JFET Dual Op Amp | 4MHz High-Speed Amplifier | SO-8 | STMicroelectronics

TL072CDT

Dual op-amp device using a high-impedance JFET input stage and bipolar output stage, supporting 6–36 V single-supply or ±3 to ±18 V dual-supply operation, with about 4 MHz gain-bandwidth, 16 V/µs slew rate, 15 nV/√Hz noise density, and 20 pA-level input bias current in an SO-8 package, ideal for audio preamplifiers, precision signal conditioning, and general-purpose analog filters.

Product Description

Product Overview

The TL072CDT is an SO-8 tape-and-reel version of STMicroelectronics’ TL07x family of low-noise JFET-input dual operational amplifiers, integrating high-voltage JFETs with bipolar transistors on a monolithic die to deliver high input impedance, low distortion, and high slew rate for demanding analog front-end designs.

With ±15 V supplies, the device offers around 4 MHz gain-bandwidth and up to 16 V/µs slew rate, with typical input bias current of about 20 pA, input offset around 3 mV, and noise density near 15 nV/√Hz at 1 kHz, making it well suited for wideband, low-noise audio and instrumentation amplifiers.

The TL072CDT supports wide common-mode and differential input ranges combined with internal frequency compensation, short-circuit protection, and latch-up-free operation, enabling stable use on both single- and dual-supply rails across general-purpose amplification, power monitoring, active filtering, audio buffering, and signal-conditioning applications.
