TL074IDR Pinout Specifications and Functions (SOIC-14 Package)
The TL074IDR has 14 pins in total. Below is the detailed pinout with their respective functions:
Pin Number Pin Name Function Description 1 Offset Null This pin is used for offset voltage nulling (trimming). It connects to an external potentiometer for adjusting the op-amp's offset voltage. 2 Inverting Input (Op-Amp 1) This is the inverting input for the first op-amp. Signals applied to this pin are inverted and amplified. 3 Non-Inverting Input (Op-Amp 1) This is the non-inverting input for the first op-amp. Signals applied to this pin are not inverted. 4 V- (Negative Power Supply) This is the negative power supply pin for the internal circuitry of the IC. 5 Output (Op-Amp 1) This is the output pin for the first op-amp. The amplified signal is taken from this pin. 6 Non-Inverting Input (Op-Amp 2) This is the non-inverting input for the second op-amp. 7 Inverting Input (Op-Amp 2) This is the inverting input for the second op-amp. 8 V+ (Positive Power Supply) This is the positive power supply pin for the internal circuitry of the IC. 9 Output (Op-Amp 2) This is the output pin for the second op-amp. 10 Inverting Input (Op-Amp 3) This is the inverting input for the third op-amp. 11 Non-Inverting Input (Op-Amp 3) This is the non-inverting input for the third op-amp. 12 Output (Op-Amp 3) This is the output pin for the third op-amp. 13 Inverting Input (Op-Amp 4) This is the inverting input for the fourth op-amp. 14 Non-Inverting Input (Op-Amp 4) This is the non-inverting input for the fourth op-amp.Complete Pin Function Description:
Pin 1 (Offset Null): This pin is typically used for adjusting the input offset voltage. The offset null function allows you to balance the op-amp by connecting a variable resistor between pins 1 and 5 (or ground), which helps eliminate any voltage difference between the inverting and non-inverting inputs when there is no input signal.
Pin 2 (Inverting Input - Op-Amp 1): The inverting input for the first op-amp in the TL074. A negative feedback loop is usually employed in the op-amp configuration, where the signal at this input gets inverted at the output pin.
Pin 3 (Non-Inverting Input - Op-Amp 1): The non-inverting input for the first op-amp. When a signal is applied here, it will be amplified without inversion.
Pin 4 (V- or Negative Power Supply): This pin connects to the negative rail or ground of the power supply. It is essential for providing the necessary voltage to operate the internal circuits of the op-amps.
Pin 5 (Output - Op-Amp 1): The output of the first op-amp. It produces the amplified signal based on the differential input between pins 2 and 3.
Pin 6 (Non-Inverting Input - Op-Amp 2): This pin is the non-inverting input of the second operational amplifier. Signals applied here will be amplified and output without inversion.
Pin 7 (Inverting Input - Op-Amp 2): The inverting input of the second op-amp. This pin, when connected to an appropriate feedback network, inverts the signal fed to it.
Pin 8 (V+ or Positive Power Supply): This pin connects to the positive voltage supply that powers the op-amp internal circuitry.
Pin 9 (Output - Op-Amp 2): This pin provides the output for the second op-amp. It produces the amplified signal based on the inputs from pins 6 and 7.
Pin 10 (Inverting Input - Op-Amp 3): The inverting input for the third op-amp. Signals applied to this pin are inverted at the output.
Pin 11 (Non-Inverting Input - Op-Amp 3): The non-inverting input for the third op-amp. Signals fed into this input are amplified without inversion.
Pin 12 (Output - Op-Amp 3): This pin provides the output for the third op-amp. The output signal is determined by the difference in voltage between pins 10 and 11.
Pin 13 (Inverting Input - Op-Amp 4): The inverting input for the fourth op-amp. This pin inverts the signal based on the feedback loop applied.
Pin 14 (Non-Inverting Input - Op-Amp 4): This pin serves as the non-inverting input for the fourth op-amp. It processes input signals that are amplified in-phase (not inverted) at the output.
