The NE5532P is an integrated circuit (IC) produced by National Semiconductor, which is now part of Texas Instruments. It's a low-noise, high-performance dual operational amplifier (op-amp) designed for audio, instrumentation, and other precision applications.
NE5532P Pinout and Function Overview
The NE5532P is in a DIP-8 package (Dual In-line Package), which means it has 8 pins. Here's a breakdown of the pin functions:
Pinout Diagram (DIP-8) Pin Number Pin Function 1 Output (Amplifier A, Inverting) 2 Inverting Input (Amplifier A) 3 Non-inverting Input (Amplifier A) 4 V- (Negative Power Supply) 5 Non-inverting Input (Amplifier B) 6 Inverting Input (Amplifier B) 7 Output (Amplifier B, Inverting) 8 V+ (Positive Power Supply) Detailed Pin Function List: Pin 1 (Output, Amplifier A, Inverting): This is the inverting output pin for the first operational amplifier (Amplifier A). It provides the output signal based on the inverting input connected to Pin 2. It’s connected to the negative feedback loop in typical op-amp circuits. Pin 2 (Inverting Input, Amplifier A): This pin connects to the inverting input of the first operational amplifier. It is where the input signal is applied in an inverting configuration, and the output at Pin 1 reflects the inverted version of the input. Pin 3 (Non-inverting Input, Amplifier A): This pin connects to the non-inverting input of the first amplifier. If this pin is used, the input signal will be amplified without inversion. Pin 4 (V-, Negative Power Supply): Pin 4 is connected to the negative power supply (often ground in many circuits). It defines the lower limit of the op-amp's voltage swing. Pin 5 (Non-inverting Input, Amplifier B): Pin 5 connects to the non-inverting input of the second operational amplifier (Amplifier B). This pin is used for non-inverting signal input in Amplifier B. Pin 6 (Inverting Input, Amplifier B): This pin connects to the inverting input of the second operational amplifier (Amplifier B). The signal applied to this pin will be inverted in the output from Pin 7. Pin 7 (Output, Amplifier B, Inverting): Pin 7 is the output of the second amplifier (Amplifier B), and the signal will be inverted based on the input applied to Pin 6. Pin 8 (V+, Positive Power Supply): Pin 8 is connected to the positive power supply. It provides the upper voltage reference for the operational amplifier.FAQ - 20 Common Questions about NE5532P
