It measures current across a shunt resistor on either the high side or low side of the supply rail, outputting a rail-to-rail voltage proportional to the sensed current. The Zero-Drift architecture keeps input offset voltage at 3 µV and input bias current at 500 pA, so the reading stays accurate even when the shunt drop is only a few millivolts. Supply current is 48 µA, which makes it a fit for battery-powered controllers and field transmitters where every microamp is budgeted. The 45 kHz gain-bandwidth product and 0.3 V/µs slew rate are sized for DC and low-frequency AC current monitoring — motor-phase currents, solenoid loads, or power-supply output rails — not for fast-switching waveforms. ## Supply range and temperature grade The part operates from a single supply between 1.7 V and 5.5 V. The -40°C to 125°C temperature range qualifies it for under-hood automotive, industrial motor-drive cabinets, and outdoor telecom enclosures where ambient heat is the constraint. ## Package and mounting Housed in a TSOT-23-8 (SOT-23-8) surface-mount package. The small footprint suits dense PCB layouts on sensor modules or battery-management boards. Standard reflow profiles for lead-free solder apply; no special handling beyond normal MSL precautions. ## Sourcing and lifecycle The INA186A3IDDFT is an active, current-production part from Texas Instruments, ROHS3 compliant. No end-of-life notice or last-time-buy window is on record. It is sourced through independent distribution and quoted to order against an RFQ — availability and current pricing are confirmed at quote time. For dual-sourcing or a higher-bandwidth option, the INA254A1IPWAR (350 kHz, 2.4 V/µs) is a pin-compatible alternative within the same Zero-Drift family, though it draws more supply current.","metaTitle":"INA186A3IDDFT Zero-Drift Current Sense Amplifier, 45 kHz","metaDescription":"TI INA186A3IDDFT current sense amplifier, Zero-Drift, 3 µV offset, 48 µA supply, -40 to 125°C.

Submit an RFQ for a current per-unit price on your target volume."},{"question":"What is the difference between INA186 and INA180?","answer":"The INA186 uses a Zero-Drift architecture that delivers lower input offset voltage (3 µV vs. higher typical values for the INA180) and lower offset drift over temperature. The INA180 is a simpler, lower-cost current sense amplifier without Zero-Drift correction. For precision monitoring over a wide temperature range, the INA186 is the better choice."},{"question":"Can the INA186A3IDDFT be used for high-side current sensing?","answer":"Yes. The INA186A3IDDFT supports both high-side and low-side current sensing. The common-mode input range extends from the negative supply to the positive supply, so it can measure current on the high side of the load without level shifting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA186A3IDDFT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA186A3IDDFT when reusing this data.
