Pinout and Function for TL062CDR

The TL062CDR is packaged in a DIP-8 (Dual in-line package) form factor with 8 pins. Below is the detailed explanation of each pin function:

Pin Number Pin Name Pin Function Description 1 Offset Null This pin is used to adjust the input offset voltage of the amplifier. Connect it to a potentiometer and adjust to reduce the input offset voltage. 2 Inverting Input (−) This is the inverting input of the operational amplifier. The input signal applied here will be inverted relative to the output signal. 3 Non-Inverting Input (+) This is the non-inverting input of the operational amplifier. The input signal applied here will be amplified without inversion. 4 V− (Negative Supply) This is the negative power supply pin for the operational amplifier. Typically connected to the ground (0V). 5 Offset Null This pin is a second offset voltage adjustment pin, similar to Pin 1. It is used in conjunction with Pin 1 for fine-tuning the offset voltage. 6 Output This is the output pin of the operational amplifier. The amplified output signal is available here. 7 V+ (Positive Supply) This is the positive power supply pin for the operational amplifier. It is usually connected to a positive voltage rail. 8 NC (No Connection) This pin is not internally connected to the chip and can be left unconnected. It is sometimes used for mechanical support in certain packaging options.
