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

After 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 uses currents in the milliampere range. This example chooses 10kΩ for RI, which means that 36kΩ is used for RF. RF value is determined by Equation 3.

Equation 3. A V   = – R F R I
