- 250 µV maximum input offset voltage delivers precise milliamp-level current measurement with minimal zero-error drift
- Integrated reference and comparators in one 8-pin MSOP package reduce external component count in overcurrent protection circuits
Applications
The LT6108AIMS8-2 is used in battery management systems and power supply monitoring circuits where accurate high-side current measurement over wide common-mode voltage ranges is needed without disrupting the ground reference. Its integrated comparator outputs simplify overcurrent protection and fault detection logic in DC-DC converters, motor drivers, and industrial power distribution units. The compact MSOP-8 package fits on space-constrained power management boards in telecommunications and server infrastructure equipment.

Frequently Asked Questions
What common-mode rejection ratio does LT6108AIMS8-2 achieve, and why is it important for high-side current sensing?
The LT6108AIMS8-2 achieves 125 dB common-mode rejection ratio, which means it can accurately measure small differential voltages across a shunt resistor sitting on a high-voltage rail (up to 100 V) while rejecting the large common-mode bus voltage that would otherwise saturate a standard op-amp.
How does the 250 µV maximum input offset voltage of LT6108AIMS8-2 affect current measurement accuracy with a low-value shunt resistor?
With a 250 µV maximum input offset voltage, measuring current through a 10 mΩ shunt resistor introduces a worst-case error of 25 mA, so designers using LT6108AIMS8-2 for milliamp-accuracy current monitoring should select shunt values of 50 mΩ or higher to keep the offset error below 1% of full-scale current.
What built-in functions does LT6108AIMS8-2 integrate beyond the current sense amplifier, and how do they reduce BOM?
The LT6108AIMS8-2 integrates an internal voltage reference and comparator outputs alongside the current sense amplifier, eliminating the need for external precision references and discrete comparators in overcurrent protection circuits, which reduces BOM by 3 to 4 components per channel on a power monitoring board.
For a 48 V telecom power supply design, is LT6108AIMS8-2 suitable for monitoring supply current on the high-side rail?
The LT6108AIMS8-2 is well suited for 48 V telecom supply current monitoring because its high common-mode input range accommodates voltages in this range and its 125 dB CMRR ensures the large 48 V bus potential does not corrupt the small differential voltage across the sense resistor, enabling milliamp-resolution measurements needed for load monitoring and protection.
