Overview

The TL072CDR is a dual JFET-input operational amplifier designed for high-speed applications requiring low input bias and offset currents. It features a high slew rate of 13V/us or up to 20V/us depending on conditions, and a 5.25 MHz gain bandwidth product. This device is widely used in high-impedance signal conditioning stages where minimal loading of the source is critical.

Why Choose This Part

The JFET input stage provides exceptionally low input bias current and input offset current, making it superior to bipolar amplifiers for high-impedance sources. It offers a wide supply voltage range from 10V to 30V total span and maintains stable performance with a typical supply current of 1.4mA per channel.

Applications

High-Impedance Sensor Interfaces
Utilizing the 65 pA input bias current to interface with piezo sensors and pH probes without significant signal loading.
Active Filter Design
Implementation of high-order Sallen-Key or State-Variable filters where the high slew rate ensures low distortion at higher frequencies.
Audio Preamplification
Used in professional audio equipment for clean signal amplification due to its low noise characteristics and high-speed performance.
Sample-and-Hold Circuits
The low input bias current minimizes voltage droop in capacitor-based hold circuits.

Getting Started

For rapid prototyping, mount the 8-SOIC package onto a DIP adapter for use with breadboards. Ensure that power supplies are decoupled with 0.1uF ceramic capacitors placed as close to the VCC+ and VCC- pins as possible to prevent oscillation during high-speed transitions.
