It delivers a 55 MHz -3dB bandwidth and a 22 V/µs slew rate while drawing 725 µA per channel. The rail-to-rail output stage (push-pull) swings close to the supply rails. Supply span runs from 2.5 V to 12 V. Operating temperature is -40°C to 85°C. ## Active production — no lifecycle risk for new BOMs The LMH6646MAX/NOPB carries an Active lifecycle status from Texas Instruments and is ROHS3 compliant. There is no NRND or last-time-buy notice. For a procurement review, this means the part can be specified into new designs without an obsolescence watch window. The NOPB suffix confirms lead-free (RoHS) construction. If you are qualifying an alternate for dual-source coverage, the TLV9362IDDFR (dual, 10.6 MHz, 25 V/µs) is a functional peer in the same package footprint — but verify pinout compatibility against your layout. ## Sourcing and availability This part is sourced through independent distribution and quoted to order against an RFQ. For a BOM line that needs a dual high-speed op-amp in SOIC-8 with active lifecycle, submit an RFQ and the desk will return a firm price and lead-time window.","metaTitle":"LMH6646MAX/NOPB TI Voltage Feedback Op-Amp, 55 MHz, 22 V/µs","metaDescription":"Texas Instruments LMH6646MAX/NOPB dual voltage-feedback op-amp, 55 MHz -3dB bandwidth, 22 V/µs slew rate, rail-to-rail output, 2.5 V to 12 V supply, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"22V/µs","Output Type":"Push-Pull, Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"55 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"725µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"650 nA","Operating Temperature":"-40°C ~ 85°C","Voltage - Input Offset":"1 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"20 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"2.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.10000","currency":"USD"},{"qty":10,"price":"$2.78000","currency":"USD"},{"qty":25,"price":"$2.62840","currency":"USD"},{"qty":100,"price":"$2.27780","currency":"USD"},{"qty":250,"price":"$2.16104","currency":"USD"},{"qty":500,"price":"$1.93908","currency":"USD"},{"qty":1000,"price":"$1.65300","currency":"USD"},{"qty":2500,"price":"$1.65300","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6c1610db6b89690d1ebad0295f4141ae.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LMH6646MAX/NOPB rail-to-rail output?","answer":"Yes, the output type is push-pull, rail-to-rail, allowing the output to swing close to both supply rails — useful in single-supply systems where headroom is limited."},{"question":"What is the closest functional equivalent for LMH6646MAX/NOPB?","answer":"The TLV9362IDDFR is a dual general-purpose op-amp with 10.6 MHz bandwidth, 25 V/µs slew rate, and rail-to-rail output in a similar package.
