What are the key features of LT6108AIMS8-2#PBF?
- 125 dB common-mode rejection ratio enables accurate current sensing on high-voltage rails from 2.9 V to 80 V without error from supply noise
- 250 µV maximum input offset voltage provides high measurement accuracy for low-value shunt resistors, reducing power loss in the sense path
- Integrated voltage reference and dual comparators in a single 8-pin MSOP eliminate external components for over-current protection threshold detection
- Current-feedback architecture with frequency compensation supports stable operation across a wide gain bandwidth product for dynamic load monitoring
What is LT6108AIMS8-2#PBF used for?
The LT6108AIMS8-2#PBF is designed for precision power monitoring and over-current protection in industrial power supplies, battery management systems, and telecom equipment operating from high-voltage rails up to 80 V. Its integrated comparators with internal reference allow direct threshold comparison of sensed current against a fixed limit, triggering protection circuits without an external comparator or DAC. The high CMRR of 125 dB also makes it suitable for motor drive current monitoring and solar inverter DC bus current measurement where large common-mode voltages are present.

Frequently Asked Questions
What common-mode voltage range does LT6108AIMS8-2#PBF support and how does its 125 dB CMRR help on high-voltage rails?
The LT6108AIMS8-2#PBF operates with a common-mode input voltage range of 2.9 V to 80 V, covering a wide range of industrial supply rails from 5 V logic to 48 V telecom buses. Its 125 dB common-mode rejection ratio means that even 80 V of common-mode swing introduces less than 3 µV of differential error referred to input, ensuring that small shunt voltage drops of 10 mV to 100 mV are measured accurately. This level of CMRR is critical in motor drives and UPS systems where high-voltage transients appear on the sense lines.
How do the integrated comparators in LT6108AIMS8-2#PBF simplify over-current protection circuit design?
The LT6108AIMS8-2#PBF integrates dual comparators with an internal voltage reference, allowing the amplified current-sense output to be compared directly against a preset threshold without external ICs. Each comparator output can drive a latch or gate signal to disable a power switch or assert a fault flag within microseconds of an over-current event. This integration reduces the component count from typically 4 to 6 ICs down to a single 8-pin MSOP device, saving board space in space-constrained power converter designs.
For a 48 V telecom power supply, what shunt resistor value works well with LT6108AIMS8-2#PBF to minimize power dissipation?
At 48 V with a typical full-load current of 10 A, a 5 mΩ shunt resistor produces a 50 mV sense voltage, well within the LT6108AIMS8-2#PBF's input range, and dissipates only 500 mW. The 250 µV maximum offset referred to input means the measurement error is less than 0.5% at 50 mV full-scale, meeting typical 1% accuracy budgets. Using a gain setting of 20 V/V, the output swings to 1 V full-scale, compatible with most 1.8 V to 3.3 V ADC input ranges used in digital power controllers.
How does LT6108AIMS8-2#PBF's 10-year YTEOL rating and MSOP package support long-lifecycle industrial designs?
The 10-year estimated end-of-life (YTEOL) rating gives industrial equipment designers confidence that LT6108AIMS8-2#PBF will remain available for service and repair spares through mid-decade planning horizons. The 8-pin MSOP package occupies approximately 5 mm x 3 mm of PCB area, making it compatible with compact power monitoring modules where the sense amplifier sits adjacent to the shunt resistor. Lead-free (PBF suffix) RoHS-compliant construction supports both commercial and industrial temperature range applications requiring REACH and RoHS documentation.
