Pinout and Pin Function for AD8066ARMZ:
Pin Number Pin Name Function Description 1 Offset Null This pin is used for external offset voltage adjustment. Connecting a potentiometer between pins 1 and 5 can help null the offset voltage of the op-amp. 2 Inverting Input (V−) The inverting input pin of the operational amplifier, where a signal can be fed for inverting amplification. 3 Non-Inverting Input (V+) The non-inverting input pin of the operational amplifier, where a signal can be fed for non-inverting amplification. 4 V− (Negative Power Supply) This is the negative power supply pin, which connects to the lower voltage source (e.g., -5V or ground in dual supply configurations). 5 Offset Null This is the complementary pin for offset adjustment, used in conjunction with pin 1. It helps to set the offset voltage to zero. 6 Output The output pin where the amplified signal is provided. 7 NC (No Connect) This pin is not connected to the internal circuitry. It can be left floating or grounded. 8 V+ (Positive Power Supply) This is the positive power supply pin, connected to the higher voltage source (e.g., +5V or +12V in dual supply configurations). 9 Inverting Input (V−) (Duplicate of Pin 2) This is used for inputting a signal for inverting amplification. 10 Non-Inverting Input (V+) (Duplicate of Pin 3) This is used for inputting a signal for non-inverting amplification. 11 Output (Duplicate of Pin 6) The output of the op-amp. 12 V− (Negative Power Supply) (Duplicate of Pin 4) The negative power supply pin. 13 Offset Null (Duplicate of Pin 1) Used for fine-tuning the offset voltage. 14 NC (No Connect) (Duplicate of Pin 7) Not connected internally. 15 V+ (Positive Power Supply) (Duplicate of Pin 8) The positive power supply. 16 Output (Duplicate of Pin 11) The output of the op-amp.FAQ for AD8066ARMZ:
