The supply span runs from 5 V to 12 V, making it compatible with common single-supply rails as well as split ±5 V or ±6 V configurations. A 200 V/µs slew rate means this amplifier can swing a 2 V peak-to-peak output at over 30 MHz before slew-rate limiting sets in — a practical limit for driving high-speed ADCs with full-scale steps. The 260 MHz gain-bandwidth product supports closed-loop gains up to 10× while still maintaining 26 MHz of small-signal bandwidth. For a unity-gain buffer driving a 10 MSPS SAR ADC input, the settling time to 0.1% is dominated by the amplifier's 120 mA output current charging the ADC's sampling capacitor, not by the slew limit. The 5 µA input bias current and 1 mV input offset voltage are typical for a bipolar-input high-speed stage; expect a DC offset contribution of several millivolts at the output, which may need a servo loop or AC coupling in precision DC paths. The part is listed as RoHS non-compliant, which matters for EU RoHS-exempt applications (military, aerospace, some medical) but may require a waiver or a lead-free alternative for commercial builds bound by the directive.","metaTitle":"LMH6655MA-TI Voltage Feedback Op-Amp, 200 V/µs Slew Rate","metaDescription":"Texas Instruments LMH6655MA-TI dual voltage feedback op-amp: 200 V/µs slew rate, 260 MHz GBP, 120 mA output, 5–12 V supply, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Bulk","Slew Rate":"200V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Voltage Feedback","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"4.5mA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"5 µA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"260 MHz","Voltage - Input Offset":"1 mV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"120 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.03","stockQuantity":0,"priceTiers":[{"qty":100,"price":"$3.03000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f7ac49d9f032ea7a801f36a6a151c1cc.pdf","sourceUrl":null},"ai":{"faq":[{"question":"When sourcing LMH6655MA-TI, what's the closest functional second-source — THS4215DRBT?","answer":"The THS4215DRBT is a single-channel voltage-feedback amplifier with a higher 350 MHz GBP and 970 V/µs slew rate, but it is not a pin-compatible or dual-channel replacement for the LMH6655MA-TI.
