Pinout and Explanation of Each Pin:

Pin 1 (V+): This is the positive voltage supply pin. The OPA4192IDR requires a positive supply voltage to function. It typically connects to a positive voltage source. Pin 2 (V-): This is the negative supply pin. This connects to a negative voltage or ground, depending on the power configuration (dual or single supply). Pin 3 (Output 1): The output signal of the first operational amplifier. This pin will provide the result of the amplification of the input signal, processed through Op-Amp 1. Pin 4 (Inverting Input 1): The inverting input for Op-Amp 1. Signals fed into this input will be inverted in phase when the output is generated. Pin 5 (Non-Inverting Input 1): The non-inverting input for Op-Amp 1. Signals fed into this input will not be inverted. Pin 6 (Offset Null 1): This pin allows fine adjustment of the offset voltage for Op-Amp 1. If you need to nullify offset voltage for more accurate measurements, you can use a potentiometer to adjust the offset. Pin 7 (V+): A repeat of Pin 1 for internal connection. Pin 8 (Output 2): The output signal of the second operational amplifier (Op-Amp 2). This is where the amplified signal will appear from the second channel. Pin 9 (Inverting Input 2): The inverting input terminal for Op-Amp 2. Pin 10 (Non-Inverting Input 2): The non-inverting input terminal for Op-Amp 2. Pin 11 (Offset Null 2): Fine offset voltage adjustment for Op-Amp 2, similar to Pin 6. Pin 12 (NC): This pin has no connection. It is typically used for packaging purposes. Pin 13 (V-): The negative voltage supply pin, identical to Pin 2. Pin 14 (Output 3): The output of the third operational amplifier (Op-Amp 3). Pin 15 (Inverting Input 3): The inverting input terminal for Op-Amp 3. Pin 16 (Non-Inverting Input 3): The non-inverting input terminal for Op-Amp 3.
