Typical Application (continued)

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 large resistors

(hundreds 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:

9.3 System Examples

When receiving low-level signals, limiting the bandwidth of the incoming signals into the system is often required.

The simplest way to establish this limited bandwidth is to place an RC filter at the noninverting terminal of the

amplifier, as shown in Figure 23.
