5.2 Non-Inverting Amplifier

A non-inverting amplifier is a configuration of the operational amplifier where the input signal is scaled by a gain (A_V) greater than 1. Non-inverting amplifiers are commonly used with small or sensitive signals, such as those from a current-sense line. The circuit shown in Figure 5-2 can be implemented using the internal resistor ladder rather than external components. The code snippet in 5.2.1 shows an example implementation with a gain of 2.
