LT6106IS5#TRMPBF

LT6106IS5#TRMPBF 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%. It 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. It is used in applications such as current shunt measurement, battery monitoring, power management, motor control, lamp monitoring, overcurrent and fault detection.
