Description
Product Overview
The TL082CP is a dual operational amplifier that combines the classic JFET‑input architecture with modern low‑power design techniques. Each channel draws only 1.4 mA typical current, allowing the device to operate efficiently in battery‑powered or energy‑constrained environments. The input bias current is exceptionally low at 30 pA typical, and the input offset current is just 5 pA, which translates to minimal error in high‑precision signal conditioning applications. Its high slew rate ensures rapid response to fast‑changing signals, making it suitable for audio, video, and instrumentation tasks where timing is critical.
Manufactured by Texas Instruments, a trusted name in analog and mixed‑signal semiconductor technology, the TL082CP is packaged in an 8‑pin DIP format with machined contact pins for reliable insertion into standard breadboards or socketed PCB designs. The included machined‑contact DIP‑8 socket further enhances mechanical stability and electrical continuity, reducing the risk of intermittent connections during prototyping or production runs. The device operates over a wide common‑mode voltage range and supports differential voltage inputs, providing flexibility for a variety of circuit topologies.
Usage
Engineers and hobbyists alike find the TL082CP valuable in a broad spectrum of applications. In audio engineering, its high slew rate and low noise floor enable clean amplification of microphone signals and line‑level sources without introducing distortion. For sensor interfaces, the low input bias current preserves the integrity of high‑impedance transducers such as thermocouples, strain gauges, and photodiodes, allowing accurate conversion of physical phenomena into electrical signals.
In instrumentation amplifiers, the TL082CP can be configured as a differential amplifier to boost small differential voltages while rejecting common‑mode noise, a crucial requirement in medical devices and industrial measurement systems. Its short‑circuit protection safeguards downstream components in case of accidental overload, extending the lifespan of the overall system. The device also excels in voltage‑feedback configurations, where its wide common‑mode range and stable gain characteristics simplify design and reduce the need for external compensation components.
Because the TL082CP is supplied in a DIP package, it is ideal for rapid prototyping on solderless breadboards, allowing designers to iterate quickly before committing to a surface‑mount layout. The machined‑contact socket ensures that repeated insertions do not degrade the pin integrity, a common issue with standard plastic sockets. This makes the TL082CP a reliable choice for educational labs, research prototypes, and low‑volume production runs where durability and repeatability are paramount.
