This combination makes it a direct-drive candidate for headphone amplifiers and active filter stages in professional audio, automotive infotainment, and industrial signal conditioning where the load impedance drops below 32 Ω. ## 32 MHz GBW and 10 V/µs slew rate — loop gain for low distortion A 32 MHz gain-bandwidth product provides enough open-loop gain at 20 kHz to keep harmonic distortion below the audible threshold in most line-level and headphone circuits. The 10 V/µs slew rate is sufficient for a 3 Vrms output swing at 20 kHz without slew-rate limiting, yet it avoids the excess noise and stability sensitivity of faster amplifiers. ## 145 mA output per channel — direct headphone drive Each of the two channels can source or sink 145 mA. That is enough to drive 32 Ω headphones to over 600 mW per channel, or 16 Ω loads to about 330 mW, without an external buffer stage. The 24-WQFN package with exposed pad helps pull heat out of the die when driving low-impedance loads continuously — the thermal pad should be soldered to a PCB copper plane. Supply current is 2.6 mA per channel, which keeps the total quiescent draw under 6 mA even with both amplifiers active. ## Active production status and sourcing posture For volume commitments or scheduled releases, a formal quotation is the appropriate next step.","metaTitle":"TI INA1620RTWT Audio Op-Amp, 32 MHz GBW, 10 V/µs","metaDescription":"Texas Instruments INA1620RTWT dual audio op-amp: 32 MHz GBW, 10 V/µs slew rate, 145 mA output per channel, 4 V to 36 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"10V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Audio","Package / Case":"24-WFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"2.6mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"1.2 µA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"32 MHz","Voltage - Input Offset":"100 µV","Supplier Device Package":"24-WQFN (4x4)","Current - Output / Channel":"145 mA","Voltage - Supply Span (Max)":"36 V","Voltage - Supply Span (Min)":"4 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.36","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.36000","currency":"USD"},{"qty":10,"price":"$7.55200","currency":"USD"},{"qty":25,"price":"$7.20040","currency":"USD"},{"qty":100,"price":"$6.25210","currency":"USD"},{"qty":250,"price":"$5.93580","currency":"USD"},{"qty":500,"price":"$5.41204","currency":"USD"},{"qty":1250,"price":"$4.94100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a893147f006addbae1e6a71e50287474.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can the INA1620RTWT be used in a headphone amplifier?","answer":"Yes. With 145 mA output current per channel, 32 MHz GBW, and a 10 V/µs slew rate, it can drive 32 Ω headphones directly to over 600 mW per channel without an external buffer. The supply range of 4 V to 36 V accommodates both single-supply and split-rail headphone designs."},{"question":"What are the alternatives to the INA1620RTWT?","answer":"The INA4290A2IRGVR is a current-sense amplifier with a different function and is not a direct audio substitute. The TLV9362IDDFR is a general-purpose dual op-amp with 10 MHz GBW and rail-to-rail output, but its 60 mA output is lower than the INA1620's 145 mA. For audio applications requiring higher output current, the INA1620RTWT remains the appropriate choice within TI's portfolio."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA1620RTWT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA1620RTWT when reusing this data.
