LT1638/LT1639

TYPICAL APPLICATIONS

proportional to the load current. As a convenient monitor,

the 2k load resistor converts the current into a voltage. The

positive supply rail, V+, is not limited to the 5V supply of

the op amp and could be as high as 44V.

The Figure 4 application uses the LT1638 in conjunction

with the LT1634 micropower shunt reference. The supply

current of the op amp also biases the reference. The drop

across resistor R1 is fixed at 1.2V generating an output

current equal to 1.2V/R1.
