LTC6101 High Voltage, High-Side Current Sense Amplifier in SOT-23 IC

LTC6101 High Voltage, High-Side Current Sense Amplifier in SOT-23 IC

The LTC®6101/LTC6101HV are versatile, high voltage, high side current sense amplifiers. Design flexibility is provided by the excellent device characteristics; 300μV Max offset and only 375μA (typical at 60V) of current consumption. The LTC6101 operates on supplies from 4V to 60V and LTC6101HV operates on supplies from 5V to 100V. The LTC6101 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. Low DC offset allows the use of a small shunt resistor and large gain-setting resistors. As a result, power loss in the shunt is reduced. The LTC6101 is available in 5-lead SOT-23 and 8-lead MSOP packages.
