Each channel can source or sink 75 mA, enough to drive a 50 Ω back-terminated line or a moderate capacitive load. The rail-to-rail output maintains signal swing near the rails, which is useful when the ADC reference is tied to the same supply. ## Package and temperature grade Housed in an 8-VSSOP (3.00 mm width) package, the LMH6643MM-NS fits tight PCB layouts but requires a fine-pitch soldering profile. ## Sourcing and supply posture Because the part is RoHS non-compliant, buyers should confirm their assembly process can accept tin-lead finish if that is the variant on hand.","metaTitle":"LMH6643MM-NS Voltage Feedback Op-Amp, 135V/µs Slew Rate","metaDescription":"TI LMH6643MM-NS dual voltage-feedback op-amp: 135V/µs slew rate, 130 MHz bandwidth, rail-to-rail output, 2.7 V to 12.8 V supply, 2.7 mA/ch.","metaKeywords":null},"attributes":{"series":"LMH®","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"LMH®","Package":"Bulk","Slew Rate":"135V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","-3db Bandwidth":"130 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"2.7mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"1.6 µA","Operating Temperature":"-40°C ~ 85°C","Voltage - Input Offset":"1 mV","Supplier Device Package":"8-VSSOP","Current - Output / Channel":"75 mA","Voltage - Supply Span (Max)":"12.8 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.58","stockQuantity":0,"priceTiers":[{"qty":190,"price":"$1.58000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f2894ebc49074f03c938a7efaf36506b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the slew rate and bandwidth of LMH6643MM-NS?","answer":"The LMH6643MM-NS delivers a 135 V/µs slew rate and 130 MHz -3 dB bandwidth, making it suitable for high-speed signal conditioning such as video amplification or fast ADC driving."},{"question":"What are the direct replacements or equivalents for LMH6643MM-NS?","answer":"A functional peer is the TLV9362IDDFR, a dual general-purpose op-amp with rail-to-rail output, but it operates at a much lower 10.6 MHz bandwidth and 25 V/µs slew rate — not a speed-equivalent replacement. For a higher-speed single-channel alternative, the THS4215DRBT offers 350 MHz and 970 V/µs but in a single-channel package. Neither is a pin-for-pin drop-in; evaluate the specific speed and channel-count requirements before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMH6643MM-NS","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMH6643MM-NS when reusing this data.
