TL072CP JFET Dual Op-Amp

Wiring Connections:

• Pin 1: Offset Null (used for adjusting offset voltage, if needed)
• Pin 2: Inverting Input of Amplifier 1
• Pin 3: Non-Inverting Input of Amplifier 1
• Pin 4: Negative Power Supply (Ground or -V)
• Pin 5: Non-Inverting Input of Amplifier 2
• Pin 6: Inverting Input of Amplifier 2
• Pin 7: Positive Power Supply (+V)
• Pin 8: Output of Amplifier 2

Power:

• Supply Voltage: Can operate with a dual supply of ±5V to ±15V or a single supply of 10V to 30V (for single-supply operation, pin 4 is connected to ground, and pin 7 is connected to the positive supply).
• Power Consumption: Low power consumption, typical of JFET-input op-amps.

Input and Output:

• Input:
  • Input Impedance: High impedance due to JFET input stage, reducing loading effects on preceding stages.
  • Input Offset Voltage: Low,  3 mV, ensuring minimal deviation in output for zero input signal.
• Output:
  • Output Voltage Swing: Can drive signals close to the power supply rails.
  • Output Current: Capable of driving loads with moderate current requirements; check datasheet for specifics.

Physical Characteristics:

• Size: 8-pin Dual In-line Package (DIP), with a standard pin spacing of 2.54 mm (0.1 inches).
• Package Dimensions: Approximately 9.3 mm x 6.35 mm x 3.3 mm (L x W x H).
• Mounting Type: Through-hole mounting for easy integration into breadboards or PCBs.

Technical Specifications:

• Common-Mode Rejection Ratio (CMRR): 100 dB (typical), ensuring that common-mode signals are effectively rejected.
• Power Supply Rejection Ratio (PSRR): 100 dB (typical), maintaining stable operation despite variations in supply voltage.
• Total Harmonic Distortion (THD): Low distortion, making it suitable for high-fidelity audio applications.

Additional Features:

• Internal Compensation: Ensures stability and wide bandwidth without the need for external compensation components.
• Temperature Range: Operates reliably over a wide temperature range,  from -40°C to +85°C.
• High Input Impedance: Minimizes loading on previous stages, allowing accurate signal amplification.

How to Use:

1. Preparation:

1. • Step 1: Determine the appropriate power supply voltage based on your circuit requirements, ensuring it falls within the ±5V to ±15V range.
   • Step 2: Gather the TL072CP op-amp, a suitable power supply, and any other components needed for your circuit (resistors, capacitors, etc.).

2. Connecting the Op-Amp:

1. • Step 1: Insert the TL072CP into the breadboard or PCB with the correct orientation to match the pin layout.
   • Step 2: Connect the Pin 4 (Negative Power Supply) to the ground of your power supply and Pin 7 (Positive Power Supply) to the positive voltage of your power supply.
   • Step 3: Wire the inputs and outputs according to your circuit design:
     • For Amplifier 1, connect the inverting input (Pin 2) and non-inverting input (Pin 3) as needed.
     • For Amplifier 2, connect the inverting input (Pin 6) and non-inverting input (Pin 5) similarly.
   • Step 4: Connect the output pins (Pin 8 for Amplifier 2) to your load or next stage in the circuit.

3. Adjustments and Testing:

1. • Step 1: If necessary, adjust the offset voltage using the Offset Null pins (Pin 1) to correct any offset errors.
   • Step 2: Power up the circuit and measure the output to ensure it meets your design specifications.
   • Step 3: Verify that the op-amp operates within its specified parameters, checking for stability and proper function.

4. Troubleshooting:

1. • Step 1: If the output is not as expected, check the connections and ensure the power supply voltages are correct.
   • Step 2: Ensure the input signals are within the allowable range and that the op-amp is not overloaded.
