For the OP275GSZ in an 8-pin SOIC package, here are the pin functions:
Pin Number Pin Name Pin Function Description 1 Offset Null (Offset Adjustment) This pin is used to adjust the offset voltage of the op-amp. It helps to minimize the offset and improve the accuracy of the amplifier. 2 Inverting Input (−) The negative input of the op-amp where the signal is applied. This is part of the differential input stage. 3 Non-Inverting Input (+) The positive input of the op-amp where the signal is also applied, in conjunction with the inverting input. 4 V− (Negative Supply) The negative power supply pin for the op-amp. This pin is connected to the negative voltage rail. 5 Output The output of the op-amp where the amplified signal is provided. 6 NC (No Connection) This pin is not connected internally to the circuit and is usually left floating or connected to the ground. 7 V+ (Positive Supply) The positive power supply pin for the op-amp. This pin is connected to the positive voltage rail. 8 Offset Null (Offset Adjustment) Another pin for offset adjustment to fine-tune the op-amp’s performance for precise applications.3. Package and Pin Count Explanation:
The OP275GSZ typically comes in an 8-pin SOIC package. This means it has 8 physical pins, and each pin has a dedicated function, as listed above. It does not have 200 pins as you might have expected, which is typical for standard operational amplifiers in smaller packages like SOIC.
