The FET input keeps input bias current at 2 pA, which matters when the source is a high-impedance microphone or piezo pickup. Supply current sits at 1.8 mA per channel, making it practical for multi-channel mixers or battery-powered recorders where every milliamp counts. That span covers everything from a 5 V USB-powered audio interface to a ±15 V studio console. The 1.8 mA quiescent current is low enough that thermal buildup in a tightly packed 8-VSSOP footprint stays manageable, even with several devices on the same board. It is not specified for under-hood or downhole temperatures, but for the vast majority of audio applications the industrial range is sufficient. No exposed thermal pad to worry about — the 1.8 mA quiescent current keeps die temperature low even in still air.","metaTitle":"OPA1641AIDGKT SoundPlus Audio Op-Amp, 11 MHz, 20 V/µs","metaDescription":"TI OPA1641AIDGKT SoundPlus audio op-amp: 11 MHz GBW, 20 V/µs slew rate, rail-to-rail output, 1.8 mA supply, -40°C to 85°C.

The rail-to-rail output stage allows the output to swing within millivolts of both supply rails, which is exactly what you need in a single 5 V or 3.3 V audio path to maximize headroom without a negative rail. The input common-mode range extends to the negative rail but stops about 1.1 V below the positive rail — fine for AC-coupled signals, but watch it if you need true zero-volt input sensing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/OPA1641AIDGKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/OPA1641AIDGKT when reusing this data.
