The LT?6107 is a versatile high side current sense ampli-
? er designed for operation over a wide temperature range.
Design ? exibility is provided by the excellent device char-
acteristics: 250μV maximum offset and 40nA maximum
input bias current. Gain for each device is set by two re-
sistors and allows for accuracy better than 1%.
The LT6107 monitors current via the voltage across an
external sense resistor (shunt resistor). Internal circuitry
converts input voltage to output current, allowing for a
small sense signal on a high common mode voltage to
be translated into a ground referenced signal. The low DC
offset allows for monitoring very small sense voltages. As
a result, a small valued shunt resistor can be used, which
minimizes the power loss in the shunt.
The wide 2.7V to 44V input voltage range, high accuracy
and wide operating temperature range make the LT6107
ideal for automotive, industrial and power management
applications. The very low power supply current of the
LT6107 also makes it suitable for low power and battery
operated applications. For applications not requiring the
wide temperature range, see the LT6106.
