Its 370 MHz -3 dB bandwidth and 2400 V/µs slew rate put it in the class of parts that handle video, radar IF, or wideband instrumentation signals without rolling off before the converter's sample rate. The 8-SOIC package keeps the layout tight — surface-mount, no heatsink needed for the 12.5 mA supply current. Temperature range spans -40°C to 125°C, so it fits outdoor telecom cabinets or engine-bay sensor interfaces as readily as a lab bench. ## Differential output — why it matters for ADC driving The differential output delivers a balanced signal pair, which directly feeds the analog input of a differential ADC without an external balun. That saves board area and avoids the phase imbalance a transformer introduces. The 65 mA output current per channel is enough to drive the sampling capacitor of a high-speed pipelined ADC and the anti-aliasing filter network. Input offset voltage is 500 µV, input bias current 4 µA — both moderate for a high-speed part; watch the bias current if your source impedance is above a few kilo-ohms.","metaTitle":"TI LMH6551MA/NOPB Voltage Feedback Amplifier","metaDescription":"Texas Instruments LMH6551MA/NOPB single voltage feedback amplifier in 8-SOIC. 370 MHz bandwidth, 2400 V/µs slew rate, differential output.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"2400V/µs","Output Type":"Differential","Mounting Type":"Surface Mount","-3db Bandwidth":"370 MHz","Amplifier Type":"Voltage Feedback","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"12.5mA","Number of Circuits":"1","Current - Input Bias":"4 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"500 µV","Supplier Device Package":"8-SOIC","Current - Output / Channel":"65 mA","Voltage - Supply Span (Max)":"12 V","Voltage - Supply Span (Min)":"3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.42","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.42000","currency":"USD"},{"qty":10,"price":"$5.76200","currency":"USD"},{"qty":25,"price":"$5.44720","currency":"USD"},{"qty":100,"price":"$4.72100","currency":"USD"},{"qty":250,"price":"$4.47892","currency":"USD"},{"qty":500,"price":"$4.01892","currency":"USD"},{"qty":1000,"price":"$3.42600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6367d9a4b9cf069f2954ebc31bc638b7.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LMH6551MA/NOPB obsolete or active?","answer":"The LMH6551MA/NOPB is active in production — no discontinuation notice, no NRND status.
