Four independent amplifiers share a single 14-SOIC package drawing 8 mA total quiescent supply current. ## Supply range and DC precision for mixed-signal boards The 5 V to 30 V supply span lets the part operate from a single 5 V rail or split ±15 V supplies commonly used in professional audio equipment. Input bias current is 250 nA typical. For a source impedance of 10 kΩ this generates a 2.5 mV DC error — comparable to the offset spec — so the designer should match the non-inverting input resistance to cancel the bias current drop, or use FET-input amplifiers if the source impedance exceeds 50 kΩ. ## Active production and compliance posture RoHS3 compliance covers the EU Directive 2015/863, and the AEC-Q100 qualification satisfies automotive customer PPAP requirements. Sourced through independent distribution channels.","metaTitle":"STMicroelectronics MC33079YDT Audio Op-Amp, 4-Ch, 15 MHz","metaDescription":"Active STMicroelectronics MC33079YDT audio op-amp, quad 15 MHz 7V/µs, -40°C to 125°C, AEC-Q100, 14-SOIC.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"7V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Audio","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"8mA","Number of Circuits":"4","Current - Input Bias":"250 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"15 MHz","Voltage - Input Offset":"2.5 mV","Supplier Device Package":"14-SO","Current - Output / Channel":"37 mA","Voltage - Supply Span (Max)":"30 V","Voltage - Supply Span (Min)":"5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.03","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.03000","currency":"USD"},{"qty":10,"price":"$1.82300","currency":"USD"},{"qty":25,"price":"$1.72000","currency":"USD"},{"qty":100,"price":"$1.46530","currency":"USD"},{"qty":250,"price":"$1.37588","currency":"USD"},{"qty":500,"price":"$1.20390","currency":"USD"},{"qty":1000,"price":"$1.13575","currency":"USD"},{"qty":2500,"price":"$1.13575","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3390ebeeb39fc908800686dc2a3d1ac1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What does the AEC-Q100 qualification mean for this op-amp?","answer":"This is the standard qualification for ICs used in under-hood or cabin electronics where the thermal profile exceeds commercial-grade limits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/MC33079YDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/MC33079YDT when reusing this data.
