Pinout and Pin Functionality (for 8-pin SOIC Package)

Here is a breakdown of the 8-pin SOIC package for the AD8034ARZ:

Pin Number Pin Name Pin Function Description 1 Offset Null Connect to a potentiometer (typically 10 kΩ) for offset voltage nulling. 2 Inverting Input (−) Inverting input of the operational amplifier. The input signal is applied here for inverting configurations. 3 Non-inverting Input (+) Non-inverting input of the operational amplifier. This pin is used to apply the signal for non-inverting configurations. 4 V− (Negative Supply) Negative supply voltage pin for the op-amp. This should be connected to the negative power supply in the circuit. 5 Output Output of the operational amplifier. This pin provides the amplified signal from the op-amp. 6 NC (No Connect) Not connected to anything internally. This pin should be left unconnected in most applications. 7 V+ (Positive Supply) Positive supply voltage pin for the op-amp. This should be connected to the positive power supply in the circuit. 8 Offset Null Connect to a potentiometer (typically 10 kΩ) for offset voltage nulling. This is the second leg of the offset nulling adjustment.
