The 5.3 mA supply current is the trade-off: you get the speed without the 10+ mA draw of a full current-feedback part, but the voltage-feedback topology means you still need to watch the feedback resistor value for stability at high closed-loop gains. The supply span runs from 4.5 V to 33 V, so it works on a single 5 V or 12 V rail, or split supplies like ±5 V. No AEC-Q100 grade here, so it is not qualified for under-hood automotive, but the industrial temperature band is enough for most chassis-mounted or indoor gear. ## Package and footprint Surface-mount only — no through-hole variant available. ## Lifecycle and compliance ROHS3 compliant, no exemptions to chase. For a new design, this part is a low-risk choice from a lifecycle standpoint — no last-time-buy clock ticking.","metaTitle":"Texas Instruments LM7121IMX/NOPB Voltage Feedback Op-Amp","metaDescription":"Texas Instruments LM7121IMX/NOPB voltage feedback op-amp, 1300 V/µs slew rate, 235 MHz -3dB bandwidth, 8-SOIC, -40°C to 85°C.

It is a functional alternative if you need slightly more bandwidth and can accept a lower slew rate. The OPA859QDSGRQ1 is a JFET-input part with 900 MHz bandwidth and 1150 V/µs slew rate, but it is AEC-Q100 qualified and comes in a different package (8-WSON). Neither is a direct pin-for-pin replacement — verify the feedback network and supply rails against your design."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM7121IMX-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM7121IMX-NOPB when reusing this data.
