# Calculate the value of R_OUT for the output R_OUT = 1e3 # 1 kΩ ( typical value )

Enter the input voltage (Vin): 10 Enter the reference voltage (Vref): 5 Enter the gain of the amplifier: 10 Calculated Component Values: R1: 1000.00 Ω R2: 500.00 Ω R_G: 100.00 Ω R_OUT: 1000.00 Ω This calculator provides the required component values for your LM3915 circuit based on the input voltage, reference voltage, and gain of the amplifier. Use these values to design and build your circuit.

# Calculate the value of R_G for the gain R_G = 1e3 / gain # 1 kΩ / gain
