The TL082B is a high-speed JFET-input dual operational amplifier designed and manufactured by STMicroelectronics, a leader in the semiconductor industry. This device features low input bias and offset currents as well as a low offset voltage, making it an ideal choice for applications requiring high input impedance and wide bandwidth. The TL082B is particularly well-suited for high-fidelity audio applications and is commonly used in signal conditioning, active filters, and other analog circuits.

Key Features

• Internally trimmed offset voltage: This ensures minimal deviation in input offset voltage, which is crucial for maintaining signal integrity in precision applications.
• Low input bias current: The JFET input stage results in significantly lower input bias currents compared to BJT input operational amplifiers, making the TL082B suitable for high-impedance sensor interfaces and buffer applications.
• High slew rate: The high slew rate of 13 V/μs (typical) allows the TL082B to handle rapid changes in input signals without distortion, which is essential for audio processing and other dynamic systems.
• Wide bandwidth: With a bandwidth of 3 MHz, this operational amplifier can be employed in a broad range of applications, including RF and audio frequency circuits.
• Low noise: The TL082B offers a low noise density, which is critical for applications such as audio pre-amplifiers and other noise-sensitive electronics.

Applications

• High-fidelity Audio Systems: The low noise and high bandwidth make the TL082B an excellent choice for audio pre-amplifiers, mixers, and other audio signal processing equipment.
• Active Filters: The operational amplifier can be used to construct various filter topologies such as low-pass, high-pass, band-pass, and notch filters.
• Analog Signal Conditioning: With its high input impedance, the TL082B is ideal for buffering and scaling analog signals in data acquisition systems.

The TL082B from STMicroelectronics is available in several packages, including DIP, SOIC, and TSSOP, providing flexibility for different design requirements. Its combination of features ensures that it remains a popular choice among designers for a wide range of analog circuit applications.
