Detailed Design Procedure

Determine the gain required by the inverting amplifier using Equation 1 and Equation 2:

Equation 1. TLV313-Q1 TLV2313-Q1 app_eq1_sbos754.gif
Equation 2. TLV313-Q1 TLV2313-Q1 app_eq2_sbos754.gif

When the desired gain is determined, choose a value for RI or RF. Choosing a value in the kilohm range is desirable for general-purpose applications because the amplifier circuit uses currents in the milliamp range. This milliamp current range ensures the device does not draw too much current. The trade-off is that very large resistors (100s of kilohms) draw the smallest current but generate the highest noise. Small resistors (100s of ohms) generate low noise but draw high current. This example uses 10 kΩ for RI, meaning 36 kΩ is used for RF. The values are determined by Equation 3:
