The 1.1 MHz GBW is enough for switching-regulator current-mode control loops switching at a few hundred kilohertz, but not for wide-bandwidth RF envelope tracking. The 15 µV input offset means you can use a smaller shunt resistor (lower power dissipation) while still getting a usable output signal at low current levels. Supply current is 370 µA typical, so it won't load down a battery-powered rail noticeably. ## Temperature range and package reality The SC-70-5 (SOT-353) footprint is compact, which helps on dense mixed-signal boards, but the small pad means thermal coupling to the shunt path is limited; keep the sense resistor close to the amp inputs to minimise IR drop on the PCB traces.","metaTitle":"INA280A5QDCKRQ1 Current Sense Amplifier, 1.1 MHz, SC-70-5","metaDescription":"TI INA280A5QDCKRQ1 current sense amplifier: 1.1 MHz GBW, 15 µV offset, 2.7-20 V supply, -40 to 125°C.
