Its 15 µV maximum input offset voltage and 0.01 pA input bias current suit microvolt-level sensor outputs. The 1 MHz gain-bandwidth product and 1 V/µs slew rate keep supply draw at 24 µA. ## Supply range and temperature grade — the deployment envelope Runs from 1.7 V to 5.5 V single supply. The -40°C to 125°C operating range covers outdoor and industrial environments. Surface-mount SC-70-5 package (SOT-353 footprint). ## Active lifecycle — no LTB clock ticking Listed as Active by TI. No last-time-buy notice, no NRND flag. For a BOM line, that means standard distribution availability and no forced redesign cycle. The e-trim™ series is TI's internal trimming technology that achieves the low offset without external nulling — it's a production feature, not a separate product family, so the part is a mainstream catalog item. ## Output drive and rail headroom Can source or sink 60 mA per channel, generous for a 24 µA quiescent part. Rail-to-rail output reaches within millivolts of the supply rails.","metaTitle":"OPA391DCKT e-trim™ Op-Amp, 1 MHz GBW, 15 µV Offset, SC-70-5","metaDescription":"TI OPA391DCKT general-purpose rail-to-rail op-amp: 1 MHz GBW, 24 µA supply, 15 µV offset, 0.01 pA bias.

The OPA391 stays the choice for precision low-power designs; the TLV9351 fits where speed matters more than quiescent current."},{"question":"What is the bandwidth of OPA391DCKT?","answer":"Gain-bandwidth product is 1 MHz, with a 1 V/µs slew rate. That combination supports gains up to about 10 at 100 kHz before the open-loop gain rolls off — adequate for audio-frequency filtering, sensor amplification, and control loops, but not for video or high-speed ADC drivers."},{"question":"What package is OPA391DCKT?","answer":"The DCKT suffix indicates a 5-pin SC-70-5 (SOT-353) surface-mount package. It is also listed as compatible with 5-TSSOP and SC-70-5 footprints — the SC-70-5 is the actual body. Tape & Reel and Cut Tape options are available for prototyping or production."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA391DCKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA391DCKT when reusing this data.
