Pin Function Table for NCV33172DR2G:

Pin Number Pin Name Function Description 1 Offset Null This pin is used to adjust the offset voltage of the op-amp. It is typically connected to a potentiometer or a variable resistor to balance the input voltage. 2 Inverting Input (-) The inverting input pin of the operational amplifier. A voltage applied here is inverted in polarity at the output. 3 Non-inverting Input (+) The non-inverting input pin of the operational amplifier. A voltage applied here maintains its polarity at the output. 4 V- (Negative Supply) This is the negative supply voltage pin for the op-amp. It is typically connected to ground or a negative voltage rail depending on the application. 5 Offset Null Similar to pin 1, this pin allows for the adjustment of the offset voltage in the op-amp circuit. Used in conjunction with pin 1 to null the offset voltage. 6 Output This pin is the output of the operational amplifier. The output voltage is determined by the difference between the inverting and non-inverting inputs and the feedback network. 7 V+ (Positive Supply) This is the positive supply voltage pin for the op-amp. It is typically connected to the positive voltage rail. 8 NC (No Connection) This is a non-connected pin that should not be used for any purpose. It does not serve any function in the circuit.

Operating Principle of NCV33172DR2G:

This IC is an operational amplifier, meaning it amplifies the difference between the voltages applied to its two input terminals (inverting and non-inverting). In this IC, the gain can be controlled using feedback resistors, and it requires a dual supply (positive and negative) for operation. The offset null pins (1 and 5) allow for precision tuning of the input offset voltage to reduce any inaccuracies in measurement.

Typical Application:

The NCV33172DR2G is used in signal conditioning, filtering, analog computing, and other circuit applications requiring precise amplification.
