Texas Instruments TL081CP JFET-Input Operational Amplifier DIP-8 4MHz

The Texas Instruments TL081CP JFET-Input Operational Amplifier DIP-8 4MHz is a high-performance JFET-input operational amplifier supplied in a convenient 8-pin DIP (Dual In-line Package). It integrates high-voltage JFET and bipolar transistors in a monolithic integrated circuit, designed to deliver precision and speed in demanding analogue applications.

Overview

The high slew rate of 13V/µs allows the amplifier to handle fast-changing signals without distortion, making it suitable for audio, signal processing, and test equipment. Its high-impedance JFET input stage minimises loading of the signal source, while low power consumption of 1.4mA per channel supports a wide supply voltage range from 7V to 36V. This flexibility suits both single and dual supply designs.

Key Features

• 13V/µs slew rate and 4MHz gain bandwidth product (3MHz unity gain)
• Low supply current of 1.4mA per channel
• Supply voltage range from 7V to 36V
• High-impedance JFET input with input bias current of 30pA and input offset current of 5pA
• Output short-circuit protection
• DIP-8 package suitable for prototyping, breadboarding, and standard through-hole PCB assembly

Applications

Well suited to portable and mains-powered designs, the TL081CP is a practical choice for prototyping, breadboarding, and standard through-hole PCB assembly. Its low input bias current and input offset current support accurate amplification in demanding analogue circuits.
