Description

The TL072CD is a low-noise JFET-input operational amplifier (op-amp) widely used in audio and signal processing applications due to its high performance and versatility. It features a low input bias current, high slew rate, and low total harmonic distortion, making it suitable for high-fidelity audio circuits. The TL072CD is part of the TL07x series, which includes several variants with different specifications.
Key characteristics include a wide supply voltage range (±3V to ±18V), low noise (typically 0.1 mV), and a high open-loop gain of up to 100 dB. It comes in a 14-pin dual in-line package (DIP) format, facilitating easy integration into various circuit designs. The op-amp’s ability to operate at a high frequency, combined with its low power consumption, makes it ideal for battery-powered devices.
Overall, the TL072CD is a reliable choice for engineers and hobbyists looking to implement quality amplification and signal conditioning in their electronic projects.

Features

7. High Output Drive Capability: Can source/sink significant current (up to ±10 mA) while maintaining linearity.
8. Package: Available in various packages, including DIP and SOIC, facilitating integration into different designs.
These features make the TL072CD suitable for audio processing, instrumentation, and other precision applications.

Package

The TL072CD is typically packaged in a dual in-line package (DIP) format, specifically the 8-pin DIP. It may also be available in surface-mount formats like SOIC or TSSOP, depending on the specific variant.

Pinout

The TL072CD is a low-noise JFET-input operational amplifier with a total of 8 pins. Here is a concise breakdown of its pin configuration and functions:
1. Pin 1 (Offset Null): Used for offset voltage adjustment.
2. Pin 2 (Inverting Input, -): Input for inverting signal.
3. Pin 3 (Non-Inverting Input, +): Input for non-inverting signal.
4. Pin 4 (V- or Negative Supply): Connection to the negative power supply voltage.
5. Pin 5 (Offset Null): Another point for offset voltage adjustment (used together with Pin 1).
6. Pin 6 (Output): Output of the operational amplifier.
7. Pin 7 (Positive Supply, V+): Connection to the positive power supply voltage.
8. Pin 8 (NC): No connection; typically used for stability in the package.
