Pin Function and Description (For the SOIC-8 Package)
Below is the detailed pinout of the TL072IDR with the specific function of each pin:
Pin Number Pin Name Function Description 1 Offset Null (1) Used to adjust the offset voltage. This pin is typically tied to a potentiometer to minimize the offset of the op-amp and achieve zero differential input voltage. 2 Inverting Input The inverting input (–) of the first op-amp section. The input signal applied to this pin will be inverted in phase at the output. 3 Non-inverting Input The non-inverting input (+) of the first op-amp section. The input signal applied to this pin will be preserved in phase at the output. 4 V− (Negative Power Supply) This is the negative supply voltage for the op-amp. It connects to the negative side of the power supply (for dual supply configurations). 5 Offset Null (2) The second pin for offset voltage adjustment. It works in conjunction with Pin 1 to minimize offset voltage, typically adjusted by a potentiometer. 6 Output The output pin of the first op-amp section. The amplified signal, with appropriate inversion or non-inversion, is provided here. 7 Non-inverting Input The non-inverting input (+) of the second op-amp section. Similar to Pin 3, this input receives the signal that is passed directly through without inversion. 8 V+ (Positive Power Supply) This is the positive supply voltage for the op-amp. It connects to the positive side of the power supply (for dual supply configurations).TL072IDR Package Pinout (SOIC-8) Summary:
