The 5 µV typical input offset voltage keeps the zero-current error low enough to resolve milliohm shunt drops in precision overcurrent detection circuits. A 400 kHz bandwidth covers most 100–200 kHz switching regulators with enough margin to reconstruct the inductor current slope for valley or peak current-mode control loops. The 90 µA input bias current is non-negligible when the shunt resistance is above 1 Ω — it adds a voltage drop that shifts the measured current reading by I_bias × R_shunt.","metaTitle":"TI INA240A4D Current Sense Amplifier, 400 kHz, 8-SOIC","metaDescription":"Texas Instruments INA240A4D current sense amplifier, 400 kHz bandwidth, 5 µV offset, 2V/µs slew rate, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Packaging":"Tube","Slew Rate":"2V/µs","Output Type":"-","Part Status":"Obsolete","Mounting Type":"Surface Mount","-3db Bandwidth":"400 kHz","Amplifier Type":"Current Sense","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"1.8mA","Number of Circuits":"1","Base Product Number":"INA240","Current - Input Bias":"90 µA","Operating Temperature":"-40°C ~ 125°C","Voltage - Input Offset":"5 µV","Supplier Device Package":"8-SOIC","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b914b1df9f950ea14b0535b1205113bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA240A4D/alternatives.json"},"ai":{"faq":[{"question":"What is the INA240A4D bandwidth and gain?","answer":"The -3dB bandwidth is 400 kHz.
