Overview

Wiring Connections:

Power Pins:
- Pin 4: Connect to negative supply voltage (V- or GND in single-supply applications).
- Pin 11: Connect to positive supply voltage (V+).
Op-Amp Input and Output:
- Each of the four Op-Amps has two input pins and one output pin.
- For each Op-Amp:
  - Inverting Input (-): Pin to apply the signal to be inverted.
  - Non-Inverting Input (+): Pin to apply the signal without inversion.
  - Output: The resulting amplified signal is available on this pin.
- Example configuration for one of the Op-Amps:
  - Pin 1 (Output 1), Pin 2 (Inverting Input 1), Pin 3 (Non-Inverting Input 1)

Power:

Supply Voltage: Operates with a dual supply voltage ranging from ±3V to ±18V, or single supply from 6V to 36V.
Power Consumption: With a low power consumption per Op-Amp, it efficiently handles amplification tasks without drawing too much current, which is essential for low-power or portable applications.

Input and Output:

Input:
- Accepts both single-ended and differential inputs.
- Ideal for high-impedance signal sources thanks to the JFET input stage, which results in low input bias current.
Output:
- Provides amplified signal outputs from each of the four Op-Amps.
- Capable of driving loads within standard application ranges, up to a few milliamps.

Physical Characteristics:

Package Type: DIP-14, suitable for through-hole mounting on printed circuit boards (PCBs).
Dimensions: Standard size for DIP-14 components, with a width of approximately 7.5mm and a length of 20mm.
Pin Count: 14 pins in total, with four Op-Amps (3 pins for each Op-Amp), plus two power supply pins.
Material: Plastic housing with metal pins for electrical connections.

Technical Specifications:

Input Offset Voltage: 3mV typical, ensures minimal deviation between the input and output signals.
Slew Rate: 13 V/μs, which defines the maximum rate at which the output voltage can change.
Gain Bandwidth Product: 3 MHz, suitable for high-speed applications.
Common Mode Rejection Ratio (CMRR): 70 dB, providing strong rejection of common-mode signals.
Total Harmonic Distortion (THD): Low, ensuring minimal signal distortion for high-accuracy amplification.

Additional Features:

Quad Configuration: Four Op-Amps in one package save space and cost in designs requiring multiple amplifiers.
Wide Supply Range: Can operate on either dual or single supply voltages, making it versatile for a range of designs.
Low Total Harmonic Distortion (THD): Ensures the amplified signal remains true to the original, which is important in audio and other analog signal processing applications.

How to Use:

Power the Device:
- For dual-supply operation, connect Pin 4 to the negative voltage (e.g., -12V) and Pin 11 to the positive voltage (e.g., +12V).
- For single-supply operation, Pin 4 can be connected to ground, and Pin 11 to the positive voltage (e.g., +12V).
Configure the Op-Amps:
- Each of the four operational amplifiers can be used independently.
- For each Op-Amp, connect the signal source to the inverting or non-inverting input as required by the application (e.g., Pin 2 and Pin 3 for Op-Amp 1).
Connect the Feedback Loop:
- For amplification with feedback, connect the output of the Op-Amp (e.g., Pin 1 for Op-Amp 1) to the inverting input via a resistor or other feedback component.
- The configuration of the feedback network will determine the gain and response of the amplifier.
Test the Output:
- Measure the output signal at the output pin (e.g., Pin 1 for Op-Amp 1). Ensure that it behaves as expected based on the input signal and the feedback network configuration.
Applications:
- Signal Amplification: Can be used to amplify analog signals, such as audio or sensor outputs.
- Filters: Suitable for use in active filter designs (e.g., low-pass, high-pass, band-pass).
- Summing Amplifiers: Combine multiple input signals into a single output.
- Comparators: Used to compare two input voltages and generate a digital output.
Safety Considerations:
- Ensure the supply voltage remains within the rated range (±3V to ±18V or single 6V to 36V).
- Avoid high temperatures beyond the operating range to prevent degradation of performance.

In conclusion, the TL074CN JFET Input Quad Op-Amp is a versatile, low-power, and high-performance operational amplifier suitable for a variety of analog signal processing tasks. Its low noise and high gain bandwidth make it ideal for audio, sensor signal processing, and general-purpose amplification applications.
