Description

The TL072 is a low-noise JFET-input operational amplifier (op-amp) widely used in audio processing, signal conditioning, and active filter applications. It features high input impedance, low distortion, and low offset voltage, making it ideal for applications requiring high fidelity.
The TL072 is available in several package types, including DIP and surface-mount configurations, and offers a bandwidth of 3 MHz with a slew rate of 13 V/μs. It operates on a wide supply voltage range, typically ±15 V, but can function effectively with single-supply voltages as low as 5 V.
With four op-amps per chip, the TL072 provides versatility in design, simplifying circuit layouts. Its low noise characteristics make it suitable for use in audio applications, such as mixers and amplifiers, while the JFET input stage minimizes bias current, preserving signal integrity.
Overall, the TL072 is a popular choice among engineers and hobbyists for its performance, reliability, and ease of use in various electronic circuits.

Features

The TL072 is a low-noise JFET-input operational amplifier known for its high performance and versatility. Key features include:
1. Low Noise: Typically 0.1 µV/°C, making it suitable for audio and precision applications.
2. Wide Bandwidth: Gain bandwidth product of 3 MHz, enabling efficient signal amplification.
3. High Slew Rate: Approximately 13 V/µs, allowing fast response to changing signals.
4. Low Total Harmonic Distortion (THD): Ensures high fidelity in audio applications.
5. Input Impedance: Very high input impedance (typical 10^12 ohms) minimizes loading on input signals.
6. Output Drive Capability: Can source and sink up to 20 mA, suitable for driving various loads.
7. Single-Supply Operation: Supports single supply voltages from ±5V to ±15V, enhancing flexibility.
8. Multiple Versions: Available in dual and quad configurations (TL072, TL074, etc.), allowing for compact circuit design.
These attributes make the TL072 ideal for applications in audio equipment, active filters, and instrumentation.

Package

The TL072 is commonly available in several package types, including Dual In-Line Package (DIP), Surface Mount Device (SMD) in SOIC, and TSSOP. The DIP version typically has 8 pins, while the SMD variations may vary in pin count and dimensions.

Pinout

The TL072 is a low-noise JFET-input operational amplifier commonly used in audio applications and signal processing. It features a 8-pin dual in-line package (DIP). The pin configuration and functions are as follows:
1. Offset Null: Adjusts the offset voltage.
2. Inverting Input (−): Input for the inverting signal.
3. Non-Inverting Input (+): Input for the non-inverting signal.
4. V-: Negative power supply voltage.
5. Offset Null: Adjusts the offset voltage (same as pin 1).
6. Output: The output of the operational amplifier.
7. V+: Positive power supply voltage.
8. NC: No connection (not used).
The TL072 typically operates with a wide supply voltage range and provides low distortion and high slew rate, making it suitable for various analog applications.
