The table below highlights its key electrical characteristics:
| Parameter | Value |
|---|---|
| Supply Voltage Range | 6V to 36V |
| Input Offset Voltage | 3mV max |
| Output Current per Channel | 40mA |
| Operating Temperature | 0°C to 70°C |
| Package Type | 8-SOIC (3.90mm width) |
This specification set makes the TL082CDT particularly well-suited for applications requiring wide dynamic range and low distortion, such as audio preamplifiers, sensor interfaces, and precision measurement systems.
Applications in Automotive and Industrial Systems
The TL082CDT's AEC-Q100 qualification opens doors to critical automotive applications where reliability is paramount. From engine control units to advanced driver assistance systems (ADAS), this amplifier maintains performance under extreme conditions. Its surface-mount packaging facilitates automated assembly processes while maintaining thermal stability across varying load conditions. In industrial settings, the device shines in programmable logic controllers (PLCs) and motor control circuits, where its 1.4mA quiescent current and rail-to-rail output swing capabilities optimize energy efficiency without compromising performance.
Why Choose the TL082CDT for Your Design?
What sets this operational amplifier apart is its unique combination of features that address modern design challenges. The JFET input structure eliminates the need for external bias compensation circuits, reducing board space requirements and component count. Its wide supply voltage range from 6V to 36V provides flexibility in both single-supply and split-rail configurations. The device's 0°C to 70°C operating temperature range ensures stable performance in commercial environments while maintaining compatibility with standard PCB materials.
For engineers working on high-impedance sensor interfaces, the TL082CDT's femtoampere-level input bias current becomes a game-changer. This characteristic minimizes errors in pH meters, photodiode amplifiers, and other measurement instruments where even minute leakage currents could compromise accuracy. The amplifier's 3mV input offset voltage specification further enhances measurement precision without requiring complex calibration routines.
Manufacturers benefit from the device's tape-and-reel packaging format (TL082CDT) that streamlines high-volume production. The 8-SOIC package strikes an optimal balance between handling convenience and space efficiency, making it ideal for portable electronics and dense PCB layouts. When compared to through-hole alternatives, the surface-mount design reduces assembly costs while improving long-term mechanical reliability.
