Applications
LT1787CMS8#PBF is designed for high-side current monitoring in battery management systems, DC motor drives, and power supply regulation circuits where the sense resistor sits above the load on rails up to 60 V. Its precision amplifier topology converts the small differential voltage across a shunt resistor into a ground-referenced output signal for ADC sampling or analog control loops. The device is commonly used in industrial power monitors, notebook PC chargers, and telecom power modules to measure load current with minimal voltage drop and high accuracy.

Frequently Asked Questions
What common-mode voltage range does LT1787CMS8#PBF support for high-side current sensing?
LT1787CMS8#PBF supports a common-mode input voltage range of 2.5 V to 60 V, allowing it to measure current on rails from low-voltage logic supplies up to 48 V telecom and industrial bus voltages. This wide range makes it useful for multi-rail power monitoring without needing separate sense amplifiers for each supply level.
How is the output gain of LT1787CMS8#PBF configured for different shunt resistor values?
LT1787CMS8#PBF uses external resistors connected to its gain pins to set the output gain, typically from 8 V/V to 500 V/V depending on resistor selection. For a 10 mΩ shunt carrying 10 A, a gain of 20 V/V produces a 2 V output swing, compatible with 2.5 V or 3.3 V ADC inputs in embedded power monitoring systems.
Which package does LT1787CMS8#PBF use and what board footprint does it occupy?
LT1787CMS8#PBF is housed in an 8-pin MSOP (micro small-outline package) with 0.65 mm lead pitch, occupying a PCB footprint of approximately 4.9 mm x 3 mm. This compact size is suited for space-constrained applications such as notebook PC charger circuits and handheld instrument power paths where board real estate is limited.
For a 48 V industrial bus monitor, what shunt resistor value should be paired with LT1787CMS8#PBF to measure up to 5 A?
At 5 A full-scale on a 48 V bus, a 20 mΩ shunt resistor produces a 100 mV differential voltage at full load, dissipating only 500 mW. Setting LT1787CMS8#PBF gain to approximately 25 V/V maps this 100 mV input to a 2.5 V full-scale output, matching a 2.5 V ADC reference while keeping power loss in the shunt below 0.1% of total power delivered.
