TL082IDR Detailed explanation of pin function specifications and circuit principle instructions

The TL082IDR is a part of the TL08x series, manufactured by Texas Instruments. It's a high-performance operational amplifier (op-amp) designed for use in a variety of analog applications.

Packaging and Pinout Specifications:

Package Type: The "D" in TL082IDR indicates the SOIC (Small Outline Integrated Circuit) package, which is a surface-mount device. Number of Pins: The TL082IDR has 8 pins (a standard dual op-amp with 8 pins in SOIC package). Function of Each Pin: Pin 1 (Offset Null): This pin is used to null the offset voltage of the op-amp, i.e., adjust the output when there is no input signal. Pin 2 (Inverting Input): This is the inverting input (–) for the first op-amp. Pin 3 (Non-Inverting Input): This is the non-inverting input (+) for the first op-amp. Pin 4 (V–): The negative supply voltage (often ground in single-supply applications). Pin 5 (Offset Null): Another pin used for offset voltage adjustment for the second op-amp. Pin 6 (Output): This is the output for the first op-amp. Pin 7 (V+): The positive supply voltage. Pin 8 (Output): This is the output for the second op-amp.
