LT6105 Datasheet PDF

●The LT6105IMS8#PBF is a precision rail-to-rail input Current Sense Amplifier with a very wide input common mode range. The LT6105 monitors unidirectional current via the voltage across an external sense resistor. The input common mode range extends from -0.3 to 44V with respect to the negative supply voltage (V-). This allows the LT6105 to operate as a high side current sense monitor or a low side current sense monitor. It also allows the LT6105 to monitor current on a negative supply voltage, as well as continuously monitor a battery from full charge to depletion. The inputs of LT6105 can withstand differential voltages up to ±44V, which makes it ideal for monitoring a fuse or MOSFET switch. Gain is configured with external resistors from 1 to 100V/V. The input common mode rejection and power supply rejection are in excess of 100dB and the input offset voltage is less than 300µV. A minimum slew rate of 2V/µs ensures fast response to unexpected current changes.
