It monitors shunt voltage on a 2.7 V to 20 V supply rail and delivers a 900 kHz bandwidth — enough to catch fast load transients in a power-stage feedback loop or a motor-phase current profile. The 15 µV input offset keeps the measurement error low across the shunt drop, and the 2 V/µs slew rate means the output settles quickly into the ADC or comparator input. ## Supply range and temperature coverage Supply span is 2.7 V to 20 V. Operating temperature range is -40°C to 125°C. ## Package and footprint Housed in a 5-lead SC-70-5 (also listed as SOT-353), the part takes minimal board area. The single-channel design keeps routing simple: one shunt input pair, supply, ground, and output. Surface-mount assembly only. ## Sourcing and lifecycle The INA280A3IDCKT is listed as Active with ROHS3 compliance. No end-of-life notice has been issued. For a BOM line that needs a current-sense amp with this bandwidth and offset, it qualifies for new production without LTB risk. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.","metaTitle":"TI INA280A3IDCKT Current Sense Amplifier, 900 kHz, SC-70-5","metaDescription":"Texas Instruments INA280A3IDCKT current sense amplifier, 2.7V to 20V supply, 900 kHz bandwidth, 15 µV offset, -40°C to 125°C.
