What is a TL84 Calculator?

The TL84 Calculator is an online utility that calculates the output voltage of a TL84-based circuit using a voltage divider principle. By entering the input voltage and resistor values, the tool instantly determines the output voltage, making circuit design and verification faster and easier.

The calculator works on the formula: Vout=Vin×R2R1+R2V_{out} = V_{in} \times \frac{R2}{R1 + R2}Vout​=Vin​×R1+R2R2​

Where:

  • VinV_{in}Vin​ = Input Voltage (V)
  • R1R1R1 = Resistor 1 (Ω)
  • R2R2R2 = Resistor 2 (Ω)
  • VoutV_{out}Vout​ = Output Voltage (V)

This formula is widely used in voltage divider circuits for TL84 applications, allowing precise voltage scaling for your projects.

How to Use the TL84 Calculator

Using the TL84 Calculator is straightforward. Follow these steps to calculate the output voltage accurately:

  1. Input the Voltage:
    Enter the input voltage (Vin) in volts. Ensure the value is positive and realistic for your circuit.
  2. Enter Resistor Values:
    • Input the value of Resistor R1 in ohms.
    • Input the value of Resistor R2 in ohms.
    Both resistors should be positive numbers for accurate calculation.
  3. Click “Calculate”:
    Press the Calculate button, and the output voltage will appear below the form.
  4. Reset if Needed:
    Click the Reset button to clear the input fields and start a new calculation.

Example of TL84 Voltage Calculation

Let’s see a practical example:

  • Input Voltage (Vin): 12V
  • Resistor R1: 4kΩ
  • Resistor R2: 6kΩ

Calculation: Vout=12×60004000+6000=12×600010000=12×0.6=7.2VV_{out} = 12 \times \frac{6000}{4000 + 6000} = 12 \times \frac{6000}{10000} = 12 \times 0.6 = 7.2VVout​=12×4000+60006000​=12×100006000​=12×0.6=7.2V

Using the TL84 Calculator, the output voltage will instantly display 7.2V, eliminating manual errors.
