It runs on a single supply from 6 V up to 38 V, making it a straightforward choice for industrial sensor interfaces, signal conditioning, and control loops that need a wide rail range without a split supply. The rail-to-rail output stage swings close to the supply rails, which helps when driving an ADC input or a low-voltage load directly. ## Key ratings and what they mean for the BOM The 2.4 MHz gain-bandwidth product and 0.35 V/µs slew rate place this part in the general-purpose band — fast enough for audio-frequency filtering, slow enough to keep noise gain under control in a 4-20 mA loop or a thermocouple amplifier. The 20 µV input offset voltage and 4 nA input bias current are typical for a precision bipolar stage; you won't need a chopper-stabilized amp unless you're after sub-µV drift. Supply current sits at 550 µA per channel, which is moderate for a 38 V-capable part — not the lowest quiescent draw, but acceptable for most panel-powered designs. ## Temperature range and environment Rated for -40°C to 125°C, the MAX9943AUA+ covers industrial enclosures, outdoor telecom cabinets, and engine-bay-adjacent electronics. The 8-uMAX/uSOP footprint (3.00 mm body width) is a common MSOP-8 land pattern, so board layout reuse across similar op-amp swaps is straightforward. The output can source or sink 20 mA per channel — enough to drive a small relay coil or an LED indicator, but not a power stage. ## Lifecycle and sourcing posture Listed as Active with ROHS3 compliance. No last-time-buy or obsolescence notice is on record. The part ships in a Tube — not Tape & Reel — so if your pick-and-place line expects a reel, factor in a tube-to-reel transfer or order a reel variant if one exists in the family.","metaTitle":"MAX9943AUA+ General Purpose Op-Amp, 2.4 MHz, 6-38 V Supply","metaDescription":"MAX9943AUA+ single general-purpose op-amp from Analog Devices. 2.4 MHz GBW, 0.35 V/µs slew rate, rail-to-rail output, 6 V to 38 V supply, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Slew Rate":"0.35V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Surface Mount","Amplifier Type":"General Purpose","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Supply":"550µA","Number of Circuits":"1","Current - Input Bias":"4 nA","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"2.4 MHz","Voltage - Input Offset":"20 µV","Supplier Device Package":"8-uMAX/uSOP","Current - Output / Channel":"20 mA","Voltage - Supply Span (Max)":"38 V","Voltage - Supply Span (Min)":"6 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.81000","currency":"USD"},{"qty":10,"price":"$2.52400","currency":"USD"},{"qty":25,"price":"$2.38600","currency":"USD"},{"qty":100,"price":"$2.06800","currency":"USD"},{"qty":250,"price":"$1.96192","currency":"USD"},{"qty":500,"price":"$1.76044","currency":"USD"},{"qty":1000,"price":"$1.48470","currency":"USD"},{"qty":2500,"price":"$1.41046","currency":"USD"},{"qty":5000,"price":"$1.35744","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a2993a7cacbddebbde227b95e0acbb36.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy MAX9943AUA+?","answer":"This part is sourced to order against an RFQ through independent distribution.
