## 5. Coding Example: Calculating Gain
If you are designing a non-inverting amplifier circuit using this part, you can use a simple script to determine your resistor values.
```python
# Simple gain calculation for non-inverting AD8038 circuit
def calculate_gain(rf, rg):
"""
Gain = 1 + (Rf / Rg)
Rf: Feedback resistor
Rg: Resistor to ground
"""
gain = 1 + (rf / rg)
return gain
rf_value = 1000 # 1k Ohm
rg_value = 1000 # 1k Ohm
print(f"The circuit gain is: {calculate_gain(rf_value, rg_value)}")
```
