8.2.2 Detailed Design Procedure

Determine the gain required by the inverting amplifier:

Equation 1. TS321 app_eq1.gif
Equation 2. TS321 app_eq2.gif

Once the desired gain is determined, select a value for RI or RF. Selecting a value in the kilohm range is desirable because the amplifier circuit uses currents in the milliamp range. This ensures the part does not draw too much current. This example selects 10 kΩ for RI which means 36 kΩ is be used for RF. This is determined by Equation 3.
