description
The LT6106 is a versatile high side current sense amplifier.The LT6106 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.Design flexibility provides excellent device features: 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 gain setting for each device consists of two resistors and allows for accuracy better than 1%.
The LT6106 monitors current via the voltage across an external sense resistor (shunt resistor).The current through the LT6106 passes through an external sense resistor (shunt resistor) voltage monitor. 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 output current of the internal circuit, the input voltage is converted into a small common-sense signal on a high common-mode voltage that allows it to be translated into a ground-referenced signal. The low DC offset allows for monitoring very small sense voltages.The low DC offset allows very small detection voltage monitoring. As a result, a small valued shunt resistor can be used, which minimizes the power loss in the shunt.As a result, a small value of the shunt resistor can be used to shunt the current, minimizing power loss.
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 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.The LT6106's current very low power supply also makes it suitable for low power and battery powered applications
