The LT6109AIMS-1#PBF from Linear Technology integrates a precision amplifier, a comparator, and a voltage reference into a single 10-MSOP package. The amplifier handles the sense-resistor voltage, the comparator provides a threshold-detect output, and the reference sets that threshold — all in one device.
Package and footprint — 10-MSOP
The package / case is listed as 10-TFSOP, 10-MSOP (0.118", 3.00mm Width), with the supplier device package confirmed as 10-MSOP. The shipping medium is Tube.
Lifecycle and compliance — no end-of-life concern
ROHS3 compliant per the listing.
Cross-shopping the LT6109 family
The LT6109 family includes several variants that differ primarily by temperature grade and output configuration. The LT6109AIMS-1#PBF is the industrial-temperature (-40°C to 85°C) version with the -1 output (the comparator output is open-drain, active-low). The LT6109HMS-1#PBF is the extended-temperature (-40°C to 125°C) version, same -1 output. If your design needs the wider temperature range for under-hood or high-ambient environments, the H-grade is the direct swap; if you need the comparator output to be push-pull or active-high, check the -2 variants (LT6109HMS-2#PBF).
