Input bias current is 100 pA, minimizing error from shunt resistor loading, and input offset voltage is 1 mV. The 2.7 V minimum supply lets it run off a 3.3 V rail with headroom, while the 5.5 V maximum covers 5 V systems without an extra LDO.","metaTitle":"INA229AIDGSR Current Sense Amplifier, 640 µA Supply","metaDescription":"Texas Instruments INA229AIDGSR current sense amplifier, single circuit, 640 µA supply current, 2.7 V to 5.5 V supply, 10-VSSOP package.","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)","Mounting Type":"Surface Mount","Amplifier Type":"Current Sense","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"640µA","Number of Circuits":"1","Current - Input Bias":"100 pA","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Input Offset":"1 mV","Supplier Device Package":"10-VSSOP","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.64","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$6.64000","currency":"USD"},{"qty":10,"price":"$5.96100","currency":"USD"},{"qty":25,"price":"$5.63560","currency":"USD"},{"qty":100,"price":"$4.88430","currency":"USD"},{"qty":250,"price":"$4.63384","currency":"USD"},{"qty":500,"price":"$4.15794","currency":"USD"},{"qty":1000,"price":"$3.54450","currency":"USD"},{"qty":2500,"price":"$3.54450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/80fdb2cb4f919b825a41ca5eec889208.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What are the alternatives to INA229AIDGSR if it's out of stock?","answer":"A functional alternative is the INA254A1IPWAR, also a current sense amplifier in the same series, but with a 350 kHz bandwidth and zero-drift architecture. The INA4290A2IRGVR offers four channels at 1.1 MHz bandwidth but is a different package and channel count. Neither is a drop-in replacement — verify pinout and gain before substituting."},{"question":"Can INA229AIDGSR replace INA219 in an existing design?","answer":"The INA219 is an I2C-interface digital current/power monitor, while the INA229AIDGSR is an analog-output current sense amplifier. They are not pin-compatible or functionally equivalent for digital bus designs. For an analog-output replacement, check the INA254A1IPWAR or INA4290A2IRGVR if the channel count matches."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA229AIDGSR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA229AIDGSR when reusing this data.
