6.5.2.1.1 Output Differential Remote Sensing Amplifier
The examples in this section show simplified remote sensing circuitry where each example uses an internal reference of 1 V. Figure 6-7 shows remote sensing without feedback resistors, with an output voltage setpoint of 1 V. Figure 6-8 shows remote sensing using feedback resistors, with an output voltage setpoint of 5 V.
