With 350 kHz gain-bandwidth and a 0.16 V/µs slew rate it's clearly a slow, stable loop amp — think current-sense amplifiers, thermocouple buffers, bridge transducer front-ends, and battery-monitoring dividers. The 21 µA supply current per channel (84 µA total for all four) keeps it viable for always-on sensor nodes and portable instruments. Rail-to-rail output swing gives you the full headroom on low-voltage rails — important when the ADC reference is the same 3.3 V rail and every millivolt of swing counts. ## Package and temperature grade — board-fit and environment The tape-and-reel delivery suits automated pick-and-place, and the ROHS3 compliance keeps it clear of the exemption-expiry issues that plague older halogenated finishes. Texas Instruments continues to manufacture this part, so the BOM line doesn't carry the obsolescence risk you'd accept on a legacy precision amp.","metaTitle":"TI OPA4330AIDR quad zero-drift op-amp, 350 kHz, 8 µV offset","metaDescription":"Texas Instruments OPA4330AIDR CMOS zero-drift quad op-amp in 14-SOIC. 350 kHz GBW, 8 µV offset, 21 µA supply, -40°C to 125°C.

The OPA4330AIDR uses the standard 14-SOIC quad op-amp pinout (outputs on pins 1, 7, 8, 14; inverting inputs on pins 2, 6, 9, 13; non-inverting inputs on pins 3, 5, 10, 12; V+ on pin 4; V- on pin 11). Check the target part's datasheet for pin-for-pin match. The OPA4374AIPWT is a 6.5 MHz CMOS quad in the same package but lacks zero-drift — its 1 mV typical offset is 125× worse, so it's not a functional replacement for precision DC applications."},{"question":"What is the slew rate of OPA4330AIDR?","answer":"The slew rate is 0.16 V/µs. This is consistent with the 350 kHz gain-bandwidth product and confirms the part is intended for low-frequency precision signals, not fast-slewing waveforms like video or high-speed data acquisition."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA4330AIDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA4330AIDR when reusing this data.
