Frequently Asked Questions - TL082CD TEXAS INSTRUMENTS
What is the TL082CD and what are its main applications?
The TL082CD is a dual JFET-input operational amplifier from Texas Instruments. It is commonly used in audio preamplifiers, active filters, signal conditioning, and instrumentation circuits due to its high input impedance and low noise.
What is the supply voltage range for the TL082CD?
The TL082CD can operate with a single supply from 7 V to 36 V or a split supply from ±3.5 V to ±18 V. This flexibility makes it suitable for various power configurations.
Can the TL082CD be used in single-supply circuits?
Yes, the TL082CD supports single-supply operation. When using a single supply, ensure the input common-mode range covers the desired signal levels, typically biased to half the supply voltage.
What is the typical slew rate of the TL082CD?
The typical slew rate is 13 V/µs. This allows the amplifier to handle fast-rising signals, making it suitable for audio and high-frequency applications.
What is the input impedance of the TL082CD?
The TL082CD has an extremely high input impedance of 10^12 Ω (typical) due to its JFET input stage. This minimizes loading on signal sources.
What is the package type and physical size?
The TL082CD is available in an SOIC-8 surface-mount package, with approximate dimensions of 5.0 × 4.0 × 1.5 mm and a weight of 0.08 g. It is suited for compact PCB designs.
What is the operating temperature range?
The TL082CD (commercial grade) has an operating temperature range of 0°C to 70°C. This covers standard commercial environments.
How should I handle the TL082CD to prevent damage?
The TL082CD is an ESD-sensitive device. Use anti-static precautions such as grounded workstations, wrist straps, and anti-static packaging. Avoid touching the pins directly.
Is the TL082CD RoHS compliant?
Yes, the TL082CD is RoHS compliant, meaning it contains no hazardous substances like lead, making it suitable for environmentally friendly electronics.
Can the TL082CD be used in audio applications?
Absolutely. The TL082CD is widely used in audio preamplifiers, mixers, and equalizers due to its low distortion, high slew rate, and low noise.
