The Texas Instruments INA199A3DCKT is a current-sense amplifier that monitors current by measuring the voltage drop across a shunt resistor. It handles common-mode voltages from -0.3 V up to 26 V.
Package and hand-solderability
The INA199A3DCKT comes in an SC-70-6 package — that's the six-lead variant of the SOT-363 footprint.
It's happy in a motor-drive enclosure, an outdoor telecom power supply, or an engine-bay ECU. The wide temperature range also means the accuracy spec holds over the full span — no cold-start drift surprises.
The INA199A3DCKT is an active, current-production part with ROHS3 compliance. No last-time-buy or obsolescence risk on the horizon.
