LT1787HVHS8#PBF

LT1787HV is a complete micropower precision high side current sense amplifier. This device monitors bidirectional currents via the voltage across an external sense resistor. A current or voltage output indicates the direction and magnitude of the sense current. This device delivers greater than a 12-bit dynamic range with ultralow 40µV input offset voltage compared to a typical 250mV fullscale input voltage. A fixed gain of 8 is set by on-board precision resistors. Input signal filtering is easily implemented with a capacitor between the FIL– and FIL+ pins. It is widely used in application such as battery monitoring, power monitoring, portable phones, cellular phones, portable test/measurement systems, battery-operated systems etc.
