Signal is applied here when non-inverting configuration is used. 4 V− (Negative Voltage Supply) The negative voltage supply pin, usually connected to the negative power rail in dual supply configurations. 5 Offset Null This pin is used in conjunction with pin 1 for offset voltage adjustment with a potentiometer. 6 Output 1 The output of the first operational amplifier. The amplified signal is provided here. 7 V+ (Positive Voltage Supply) The positive voltage supply pin, usually connected to the positive power rail in dual supply configurations. 8 Output 2 The output of the second operational amplifier. The amplified signal is provided here.Circuit Principle:
The TL062CDR consists of two independent operational amplifiers (op-amps) housed in a single IC. These operational amplifiers can be used individually in various configurations such as inverting, non-inverting, differential, integrator, and others. The input pins (pins 2 and 3 for op-amp 1, pins 2 and 3 for op-amp 2) are used to apply the signal, while the output pins (pins 6 and 8) deliver the processed signal.
The power supply pins (V+ on pin 7 and V- on pin 4) provide the necessary voltage to the op-amps. The offset null pins (pins 1 and 5) allow for fine-tuning of the offset voltage, which is useful in precision applications.
