The LT®6105 is a micropower, precision current sense amplifier with a very wide input common mode range. 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 1V/V 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.
