Packaging and Pin Function Specifications for AD706JRZ
The AD706JRZ is typically offered in a DIP-8 package (8-pin dual in-line package). Below is the detailed explanation of the 8-pin configuration for the AD706JRZ, including the function of each pin, and a list of FAQs.
Pin Configuration and Function Pin Number Pin Name Pin Function Description 1 Offset Null (N.C.) This is the offset null pin. It is used to adjust the input offset voltage. A potentiometer or resistor network can be connected to this pin to reduce the offset voltage to 0V. 2 Inverting Input (−) This is the inverting input pin. A signal applied here will be inverted in polarity at the output. 3 Non-Inverting Input (+) This is the non-inverting input pin. A signal applied here will not be inverted at the output. It adds in-phase to the output. 4 V− (Negative Supply) This is the negative voltage supply pin. It is connected to the negative power supply voltage for the operational amplifier. 5 Offset Null (N.C.) This is another offset null pin, often used in conjunction with pin 1 to provide further fine-tuning of the offset voltage. 6 Output (Vout) This is the output pin of the operational amplifier. The amplified signal will be available here, either inverted or non-inverted depending on the input configuration. 7 V+ (Positive Supply) This is the positive voltage supply pin. It is connected to the positive power supply voltage for the operational amplifier. 8 NC (No Connection) This is a no-connect pin, which means it has no function in this specific model and does not need to be connected. Pin Function Overview The AD706JRZ operates as a precision, low-noise operational amplifier designed for applications requiring high accuracy and stability. It has both inverting and non-inverting inputs, allowing it to be used in various configurations for signal amplification. It also features offset null pins to fine-tune the input offset voltage, making it ideal for high-precision measurements.FAQs about AD706JRZ Pin Functions
