The LT6105 is a current sense amplifier whose inputs can operate over a range of -0.3V to 44V independent of the supply voltage.
The document introduces the LT6105 as an ideal current sense amplifier capable of monitoring small differential voltages on top of large varying common mode voltages. It highlights that with a reasonable supply voltage (e.g., 3V), the device can accurately monitor inputs across a wide range from -0.3V to 44V.
The inputs can monitor voltages from -0.3V to 44V regardless of the supply voltage.
The output accuracy is specified as 25mV per mA of current.
The circuit uses a 4.99k ohm pull-up resistor to keep inputs within range.
