It monitors current via a shunt resistor and outputs a voltage proportional to the sensed current, making it a direct fit for motor-drive phase monitoring, solenoid current regulation, and DC-DC converter output sensing where the 4.5 V to 5.5 V supply span matches a 5 V rail. ## 1.2 MHz bandwidth, 3V/µs slew rate The -3 dB bandwidth of 1.2 MHz and slew rate of 3 V/µs define the usable signal frequency — switching power supplies running at 200-500 kHz fall within the passband, so the amplified shunt waveform reaches the controller with minimal phase lag. The 40 mA output per channel can drive the ADC input directly without a separate buffer. Input offset voltage is 500 µV and input bias current is 137.5 µA — the bias current flows through the shunt resistor and adds a voltage drop that must be accounted for in the measurement error budget at low shunt values. Supply current is 5.8 mA typical, which keeps the thermal contribution low in the -40°C to 125°C operating range — no derating concern in a confined enclosure. ## Active production, tube delivery Supplied in tube packaging, the 8-MSOP footprint (0.118-inch width, 3.00 mm) suits standard pick-and-place assembly. The surface-mount package is ROHS3 compliant.","metaTitle":"LT1999HMS8-50F#PBF Current Sense Amplifier, 1.2 MHz, 8-MSOP","metaDescription":"Analog Devices LT1999HMS8-50F#PBF current sense amplifier, 1.2 MHz bandwidth, 3V/µs slew rate, 4.5-5.5 V supply, -40 to 125°C, 8-MSOP.","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":"3V/µs","Mounting Type":"Surface Mount","-3db Bandwidth":"1.2 MHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"5.8mA","Number of Circuits":"1","Current - Input Bias":"137.5 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"500 µV","Supplier Device Package":"8-MSOP","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"4.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.64","stockQuantity":15,"priceTiers":[{"qty":1,"price":"$7.64000","currency":"USD"},{"qty":10,"price":"$6.90500","currency":"USD"},{"qty":25,"price":"$6.58400","currency":"USD"},{"qty":100,"price":"$5.71700","currency":"USD"},{"qty":250,"price":"$5.46008","currency":"USD"},{"qty":500,"price":"$4.97828","currency":"USD"},{"qty":1000,"price":"$4.54500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/93c8edf8102ecd7455e01110a22d8345.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Can LT1999HMS8-50F#PBF replace LT1999HMS8-50?","answer":"The suffix #PBF indicates ROHS3 compliance — the base die and package are the same as the non-PBF variant, so a direct replacement is electrically identical as long as the assembly process accepts lead-free parts."},{"question":"What is the bandwidth of LT1999HMS8-50F#PBF?","answer":"The -3 dB bandwidth is 1.2 MHz, which covers the switching frequencies of most DC-DC converters and motor-drive PWM stages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT1999HMS8-50FPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT1999HMS8-50FPBF when reusing this data.
