DESCRIPTION

The LT®6107 is a versatile high side current sense amplifier

designed for operation over a wide temperature range.

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 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.
