LTC6102HVHMS8#TRPBF

LTC6102HV is a precision zero drift current sense, versatile, high voltage, high side current sense amplifier. It is a high supply voltage rating allows their use in many high side applications, while the low drift and offset ensure accuracy across a wide range of operating conditions. It monitors current via the voltage across an external sense resistor (shunt resistor). Internal circuitry converts input voltage to output current, allowing a small sense signal on a large common mode voltage to be translated to a ground-referred signal. Low DC offset allows the use of very low shunt resistor values and large gain-setting resistors. As a result, power loss in the shunt is reduced. The wide operating supply and high accuracy make the LTC6102 ideal for a large array of applications, from automotive, to industrial and power management. Application includes current, shunt measurement, battery monitoring, remote sensing, load protection, motor control, automotive controls.
