The small 2.0 mm × 2.1 mm footprint demands careful decoupling — a 0.1 µF ceramic close to the supply pin keeps the 370 µA quiescent current free of rail noise. Tape & Reel (TR) and Cut Tape (CT) options are both available from the distributor, covering prototype pick quantities and production reels alike. ## What the key ratings mean for your shunt measurement As a dedicated current-sense amplifier, the INA290A1QDCKRQ1 amplifies the voltage drop across a shunt resistor with a fixed gain — the 1.1 MHz gain-bandwidth product means it settles fast enough for DC and low-frequency load steps, but not for sub-microsecond current spikes. The 5 µV input offset translates to a 0.5% error on a 1 mV shunt drop, typical for precision monitoring.","metaTitle":"TI INA290A1QDCKRQ1 Current Sense Amplifier, SC-70-5, Active","metaDescription":"Texas Instruments INA290A1QDCKRQ1 current sense amplifier, single circuit, SC-70-5 package, 2.7-20 V supply, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Current Sense","Package / Case":"5-TSSOP, SC-70-5, SOT-353","lifecycle_stage":"eol_hot","Current - Supply":"370µA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"1.1 MHz","Voltage - Input Offset":"5 µV","Supplier Device Package":"SC-70-5","Voltage - Supply Span (Max)":"20 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.32","priceTiers":[{"qty":1,"price":"$3.32000","currency":"USD"},{"qty":10,"price":"$2.97800","currency":"USD"},{"qty":25,"price":"$2.81560","currency":"USD"},{"qty":100,"price":"$2.44020","currency":"USD"},{"qty":250,"price":"$2.31508","currency":"USD"},{"qty":500,"price":"$2.07730","currency":"USD"},{"qty":1000,"price":"$1.75195","currency":"USD"},{"qty":3000,"price":"$1.66435","currency":"USD"},{"qty":6000,"price":"$1.60178","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0c86045627870dfb964658dc6cca9047.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA290A1QDCKRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA290A1QDCKRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA290A1QDCKRQ1 when reusing this data.
