Overview
LT1787/LT1787HV Precision, High Side Current Sense Amplifiers FEATURES s s s s s s s s s DESCRIPTIO Input Offset Voltage: 75µV (Max) 60V Supply Operation (LT1787HV) 12-Bit Dynamic Range Operating Current: 60µA User-Selectable External Sense Resistor Bidirectional High Side Current Sensing Unidirectional or Bidirectional Output Input Noise Filtering Available in 8-Lead SO and MSOP Packages U APPLICATIO S s s s s s s Battery Monitoring Power Monitoring Portable Phones Cellular Phones Portable Test/Measurement Systems Battery-Operated Systems The LT ®1787 is a complete micropower precision high side current sense amplifier.
The LT1787 monitors bidirectional currents via the voltage across an external sense resistor.
A current or voltage output depicts the direction and magnitude of the sense current.
The LT1787 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 onboard ...
