It delivers rail-to-rail output swing across a 4.5 V to 36 V supply range, making it a flexible building block for signal conditioning in industrial control, motor-drive feedback, and test equipment. The 14-SOIC package fits standard surface-mount assembly lines, and the -40°C to 125°C temperature range covers most industrial and automotive cabin environments. ## Key ratings and what they mean for the BOM Rail-to-rail output with 65 mA per channel drive lets this op-amp swing close to the supply rails into moderate loads — useful for driving ADC inputs, multiplexers, or short cable runs without a separate buffer stage. The 70 pA input bias current is low enough for most high-impedance sensor interfaces, but not as low as CMOS-input competitors. ## Package and mounting The 14-SOIC package (3.90 mm body width) is a standard footprint shared by many quad op-amps. No special pad geometry or thermal vias are needed for this 1.3 mA per channel part. ## Sourcing and lifecycle TI lists the OPA4189IDR as Active — no end-of-life notice, no last-time-buy window. For BOM planning, this means no near-term obsolescence risk; you can qualify it for new designs without a sunset clock.","metaTitle":"TI OPA4189IDR quad op-amp, 14 MHz GBP, 20 V/µs slew rate","metaDescription":"Quad general-purpose op-amp, 14 MHz gain bandwidth, 20 V/µs slew rate, rail-to-rail output, 4.5–36 V supply.

The OPA4189IDR offers a slightly higher 14 MHz GBP and 20 V/µs slew rate at a lower supply current per channel (1.3 mA vs 1 mA for the OPA4192). Choose the OPA4189 when speed per milliamp matters more than sub-100 µV offset."},{"question":"Can OPA4189IDR replace OPA4192?","answer":"In many general-purpose circuits, yes — both are quad op-amps in 14-SOIC with rail-to-rail output and 4.5 V to 36 V supply range. However, the OPA4189 has a higher 800 µV max offset versus the OPA4192's typical 5 µV, so precision DC applications may need a layout or gain adjustment. Check the offset error budget before swapping."},{"question":"What is OPA4189IDR's listed slew rate?","answer":"The slew rate is 20 V/µs. This supports large-signal bandwidth up to roughly 300 kHz at 20 Vpp output, adequate for fast multiplexer switching or driving ADC inputs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA4189IDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA4189IDR when reusing this data.
