Its 2 µV input offset voltage and 850 kHz gain-bandwidth product make it a strong fit for applications where you need both DC accuracy and the bandwidth to capture switching-load transients — think motor current monitoring in industrial drives, solenoid current in automotive transmission controllers, or load current in 12 V and 24 V power distribution. ## Slew rate and bandwidth — what they mean for transient response The 2 V/µs slew rate and 850 kHz gain-bandwidth product define how fast this amplifier responds to a step change in current. For a typical shunt voltage swing, the output settles in a few microseconds — fast enough to catch overcurrent events from short circuits or inrush in most power systems. ## Supply range and quiescent current — rail flexibility vs power budget The 2.7 V to 20 V supply span means this part can run directly off a logic rail or a system bus — no secondary regulator needed for the sense amplifier itself. The 680 µA quiescent supply current is moderate for most line-powered or moderately battery-powered designs. ## Package and footprint — 8-VSSOP for space-constrained boards The INA2290A4IDGKT comes in an 8-VSSOP package (the MSOP-8 variant with 0.118-inch / 3.00 mm body width). It is a surface-mount part intended for reflow assembly. The small footprint suits multi-channel boards where board area is tight, but the fine pitch means the PCB layout should follow the manufacturer's recommended land pattern — particularly for the thermal pad connection if one exists in the package outline. ## Lifecycle and compliance — active, RoHS3, no end-of-life concern No successor or second-source alternate is recorded in the official cross-reference — the part is sole-sourced from Texas Instruments. For production BOMs, qualifying the quad-channel INA4290A2IRGVR requires a separate design validation as it is a four-channel device with different pinout and package.","metaTitle":"Texas Instruments INA2290A4IDGKT Current Sense Amplifier","metaDescription":"Texas Instruments INA2290A4IDGKT current sense amplifier, single circuit, 2 µV offset, 850 kHz GBP, 2 V/µs slew, 2.7-20 V supply, -40 to 125°C, 8-VSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2V/µs","Mounting Type":"Surface Mount","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"680µA","Number of Circuits":"1","Current - Input Bias":"20 µA","Operating Temperature":"-40°C ~ 125°C (TA)","Gain Bandwidth Product":"850 kHz","Voltage - Input Offset":"2 µV","Supplier Device Package":"8-VSSOP","Voltage - Supply Span (Max)":"20 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.37","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.37000","currency":"USD"},{"qty":10,"price":"$5.72200","currency":"USD"},{"qty":25,"price":"$5.40920","currency":"USD"},{"qty":100,"price":"$4.68800","currency":"USD"},{"qty":250,"price":"$4.44756","currency":"USD"},{"qty":500,"price":"$3.99078","currency":"USD"},{"qty":1250,"price":"$3.40200","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8ef3b1b8c3b67c630187bad3db9f54d1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is INA2290A4IDGKT RoHS compliant?","answer":"Yes, it is ROHS3 compliant per the official lifecycle record."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA2290A4IDGKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA2290A4IDGKT when reusing this data.
