n Available in 8-Lead DFN and MSOP Packages The LT®6100 is a complete micropower, precision, high
side current sense amplifier. The LT6100 monitors unidirectional currents via the voltage across an external sense
resistor. Fixed gains of 10, 12.5, 20, 25, 40, 50V/V are
obtained by simply strapping or floating two gain select
pins. Gain accuracy is better than 0.5% for all gains. n The LT6100 sense inputs have a voltage range that extends
from 4.1V to 48V, and can withstand a differential voltage
of the full supply. This makes it possible to monitor the …
