8.2.1.2 Detailed Design Procedure

Determine the gain required by the inverting amplifier:

Equation 1. A V   =   V O U T V I N
Equation 2. A V   =   1.8 - 0.5   =   - 3.6

Once the desired gain is determined, choose a value for RI or RF. Choosing a value in the kΩ range is desirable because the amplifier circuit will use currents in the milliamp range. This causes the part will not draw too much current. This example will choose 10kΩ for RI which means 36kΩ will be used for RF. This was determined by Equation 3.

Equation 3. A V   =   -   R F R I
