... Shunt feedback through R converts this current to a voltage with gain of approx- F imately 2.2kΩ (1.0kΩ for MAX3267). Schottky diodes clamp the output voltage for large input currents, as shown in Figure 3. The voltage amplifier converts single-ended signals to differential signals and introduces a voltage gain. ...
