DESCRIPTION
The LT®6106 is a versatile high side current sense amplifier.
Design flexibility is provided by the excellent device
characteristics: 250μV maximum offset and 40nA maximum
input bias current. Gain for each device is set by two
resistors and allows for accuracy better than 1%.
The LT6106 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 LT6106
ideal for automotive, industrial and power management
applications. The very low power supply current of the
LT6106 also makes it suitable for low power and battery
operated applications.
