Pinout and Detailed Function of All 8 Pins for OP07CDR (SOIC-8):
Pin Number Pin Name Pin Function Description 1 Offset Null This pin is used to adjust the output offset voltage. Connecting a potentiometer between this pin and pin 5 allows for offset voltage trimming in precision applications. 2 Inverting Input (V-) The inverting input of the operational amplifier. The voltage at this pin is inversely related to the output voltage based on the gain of the op-amp circuit. 3 Non-Inverting Input (V+) The non-inverting input of the operational amplifier. This pin is used for input signals that will appear as-is (i.e., the output voltage follows the input voltage). 4 V- (Negative Supply) This is the negative power supply pin of the op-amp. It typically connects to ground or a negative supply voltage, depending on the configuration of the circuit. 5 Offset Null The second pin for adjusting the output offset voltage. A potentiometer connected between pins 1 and 5 allows for precision offset adjustment. 6 Output The output pin of the op-amp, where the amplified signal is delivered. This pin reflects the signal processing and gain characteristics based on the input signals. 7 V+ (Positive Supply) This is the positive power supply pin of the operational amplifier. It connects to a positive voltage source to power the internal circuitry of the op-amp. 8 NC (No Connect) This pin is typically not used for any connection, providing physical space for layout. It's left floating in most applications.FAQ (Frequently Asked Questions):
