That makes it a fit for precision motor-phase current loops, solenoid diagnostics, and battery charge/discharge monitoring where the shunt voltage is small and the accuracy target is tight. ## Bandwidth and slew rate — transient capture window The 400 kHz -3 dB bandwidth and 2 V/µs slew rate set the device's ability to reproduce fast current edges. A 1 A/µs current ramp through a 10 mΩ shunt produces a 10 mV/µs signal at the input — the INA240A4PWR's slew rate is 200× faster, so the output tracks the event with negligible lag. This matters for overcurrent detection in switching regulators or short-circuit protection in motor drives where the fault must be captured within a few microseconds. Supply current is 1.8 mA, low enough to keep the thermal budget clean in a densely populated 8-TSSOP board. ## Package and marking — provenance check Supplied in 8-TSSOP with a 4.40 mm body width — the same footprint as other INA240 gain options. The base product number INA240 is consistent across the family; the suffix A4 identifies the gain variant.","metaTitle":"TI INA240A4PWR Current-Sense Amplifier, 400 kHz, 2 V/µs","metaDescription":"TI INA240A4PWR current-sense amplifier, 5 µV offset, 400 kHz bandwidth, 2 V/µs slew rate. -40°C to 125°C, 8-TSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"2V/µs","Output Type":"-","Mounting Type":"Surface Mount","-3db Bandwidth":"400 kHz","Amplifier Type":"Current Sense","Package / Case":"8-TSSOP (0.173\\\", 4.40mm Width)","Product Status":"Active","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-TSSOP","Voltage - Supply Span (Max)":"5.5 V","Voltage - Supply Span (Min)":"2.7 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/b914b1df9f950ea14b0535b1205113bf.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/INA240A4PWR/alternatives.json"},"ai":{"faq":[{"question":"Does INA240A4PWR need external resistors?","answer":"The INA240A4PWR is a complete current-sense amplifier — it does not require external gain-setting resistors. The gain is fixed internally (100 V/V for the A4 variant). Only the shunt resistor and supply decoupling capacitors are needed externally."},{"question":"Can INA240A4PWR replace INA240A1PWR or INA240A3PWR?","answer":"Yes, the INA240A4PWR is pin-compatible with the INA240A1PWR and INA240A3PWR — same 8-TSSOP footprint, same supply range, same bandwidth. The only difference is the fixed gain: the A1 is 20 V/V, the A3 is 50 V/V, and the A4 is 100 V/V. If the gain code can be accommodated in the downstream ADC range or the shunt value is adjusted, the swap is straightforward."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/INA240A4PWR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/INA240A4PWR when reusing this data.
