Low Sense Voltage Operation
Figure 4 shows the simplest circuit configuration in which
the LT6100 may be used. While VOUT (output voltage)
increases with positive sense current, at VSENSE = 0V,
the LT6100’s buffered output can only swing as low as
VOL = 15mV. The accuracy at small sense voltages can be
improved by selecting higher gain. When gain of 50V/V
is selected, as shown in Figure 7, VOUT leaves the clipped
region for a positive VSENSE greater than 1mV compared
to 2.5mV for gain of 10V/V (see Figure 6).
