Linear Technology announces the LT6105, a precision current sense amplifier with an input common mode range that extends from ל.3 V below V-, up to 44V above V-. The common mode range of the LT6105 is independent of the positive supply voltage, making it ideal for a wide range of applications. As a result, the LT6105 can operate as a high-side or a low-side current sense monitor. The LT6105 can continuously monitor current during a load short or power supply failure, as well as continuously monitor a battery from full charge to epletion. The LT6105 can directly monitor the current on a negative supply voltage and because the inputs of LT6105 can withstand differential voltages up to 䕐V, it is suitable for monitoring loads connected through a fuse or a MOSFET switch. The LT6105 offers excellent precision with only 300µV of input offset voltage and only 0.5µV/°C of input offset drift. Any gain between 1 to 100 V/V can be designed with external resistors and gain error is limited to less than 1% maximum. The LT6105 operates with an independent supply voltage of 2.85 V to 36 V and draws only 150µA. When powered down, the sense pins are biased off, which prevents any loading of the sense resistor, irrespective of the sense voltage.
