Overview

The TL072CP is a dual J-FET input operational amplifier designed for high-fidelity audio and industrial applications. It features a high slew rate of 13V/us or more and a low input bias current of 65 pA, making it ideal for high-impedance signal paths. This device is housed in a standard 8-pin PDIP package, facilitating easy breadboarding and through-hole assembly.

Why Choose This Part

The TL072CP offers a significant advantage in high-impedance applications due to its J-FET input stage, which minimizes input bias current to just 65 pA. With a 5.25 MHz gain bandwidth product and robust output short-circuit protection, it provides a reliable balance of speed and durability. Its wide operating voltage range up to 20V VDD allows for high headroom in analog signal processing.

Applications

High-Fidelity Audio Mixers
Used in pre-amplifier stages and active filters to maintain signal integrity with low harmonic distortion.
Servo Drive Control
Provides fast response times in motor control feedback loops due to its 13V/us slew rate.
Solar Inverters
Utilized in signal conditioning for string and central inverters where high input impedance is required.
UPS Signal Conditioning
Maintains accuracy in voltage and current monitoring within single-phase and three-phase uninterruptible power supplies.
Battery Test Equipment
Acts as a high-precision buffer or amplifier for sensing low-level signals from battery cells.

Getting Started

When prototyping with the TL072CP, ensure proper decoupling capacitors (typically 0.1uF ceramic) are placed close to the supply pins to prevent oscillation. Since this is a through-hole PDIP package, it can be plugged directly into standard solderless breadboards for rapid circuit validation. Engineers should refer to the Texas Instruments datasheet for specific offset voltage nulling techniques if high DC precision is required.
