3. Pin Function List (for 8 pins in the VSSOP package)
Below is a detailed pinout and function description for each pin of the OPA2376AIDGKR:
Pin Number Pin Name Pin Function Description 1 Inverting Input (–) The inverting input terminal of the operational amplifier. It is used to apply the input signal that will be inverted by the op-amp. This pin has a high input impedance. 2 Non-inverting Input (+) The non-inverting input terminal of the operational amplifier. It is used to apply the input signal that will be amplified without inversion. It also has a high input impedance. 3 Output The output terminal of the operational amplifier. This is where the amplified signal is provided based on the difference between the non-inverting and inverting inputs. 4 V– (Negative Power Supply) The negative supply voltage for the operational amplifier. This pin is connected to the negative rail (usually ground or a negative supply voltage). 5 Offset Null Used for adjusting the offset voltage of the amplifier. If offset adjustment is needed, this pin can be connected to a potentiometer to nullify any offset voltage. 6 V+ (Positive Power Supply) The positive supply voltage for the operational amplifier. This pin is connected to the positive rail (usually +3V to +36V). 7 No Connect This pin is not connected internally and has no function. It is a reserved pin for physical package constraints or to maintain symmetry in pin layouts. 8 NC (No Connect) Similar to pin 7, this pin does not have any electrical function. It is not connected internally and is simply provided as part of the package layout.4. Frequently Asked Questions (FAQs)
