Circuit Implementation Example Below is a simple representation of how to wire the 3404G as a **Non-Inverting Amplifier**: ```c /* Basic Logic for Gain Calculation */ Gain = 1 + (Rf / Rin) Vout = Vin * (1 + (Rf / Rin)) ``` 1. Connect the input signal to **Pin 3 (+INPUT A)**. 2. Connect a resistor (**Rin**) from **Pin 2 (-INPUT A)** to ground. 3. Connect a feedback resistor (**Rf**) between **Pin 1 (OUTPUT A)** and **Pin 2**. 4. Supply power to **Pin 8 (V+)** and **Pin 4 (GND)**.
