... SOT23, 3V/5V, Single-Supply, Rail-to-Rail Instrumentation Amplifiers Applications Information Setting the Gain (MAX4460) The MAX4460 gain is set by connecting a resistive- divider from OUT to GND, with the center tap connect (Figure 2). The gain is calculated by: Gain = Because FB has less than 100pA IB, high-valued resis- tors can be used without significantly affecting the gain accuracy. The sum of resistors (R1 + R2) near 100kΩ ...
