It swings rail-to-rail on the output, runs on a single supply from 2.5 V to 44 V, and draws 205 µA per channel — a combination that fits signal-conditioning stages in industrial controls, loop-powered transmitters, and battery-backed analog I/O. Gain bandwidth product is 1.2 MHz and slew rate is 0.4 V/µs. Input offset voltage is 250 µV and input bias current is 20 nA. Each output can source or sink 40 mA. Operating temperature range is -40°C to 85°C. ## Supply voltage range — what it unlocks Supply span is 2.5 V to 44 V. This allows use in various voltage domains without a secondary regulator. ## Through-hole package — board-level fit The 8-DIP package (0.300\" body width, 7.62 mm lead pitch) is a standard footprint that mates with breadboards, prototype sockets, and legacy through-hole PCBs. Tube delivery keeps leads straight for automated insertion or manual soldering. ## Lifecycle and compliance The part carries an Active product status with ROHS3 compliance. No last-time-buy window is announced, and no official successor has been designated. For new designs or BOM continuity, this part is a stable choice without near-term obsolescence risk.","metaTitle":"LT1638IN8#PBF Dual Op-Amp, Rail-to-Rail, 1.2 MHz, 8-DIP","metaDescription":"LT1638IN8#PBF dual general-purpose op-amp with rail-to-rail output, 1.2 MHz GBW, 0.4 V/µs slew rate, 2.5 V to 44 V supply range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tube","Slew Rate":"0.4V/µs","Output Type":"Rail-to-Rail","Mounting Type":"Through Hole","Amplifier Type":"General Purpose","Package / Case":"8-DIP (0.300\\\", 7.62mm)","lifecycle_stage":"eol_hot","Current - Supply":"205µA (x2 Channels)","Number of Circuits":"2","Current - Input Bias":"20 nA","Operating Temperature":"-40°C ~ 85°C","Gain Bandwidth Product":"1.2 MHz","Voltage - Input Offset":"250 µV","Supplier Device Package":"8-PDIP","Current - Output / Channel":"40 mA","Voltage - Supply Span (Max)":"44 V","Voltage - Supply Span (Min)":"2.5 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.44","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$7.44000","currency":"USD"},{"qty":10,"price":"$6.72300","currency":"USD"},{"qty":25,"price":"$6.41040","currency":"USD"},{"qty":100,"price":"$5.56610","currency":"USD"},{"qty":250,"price":"$5.31592","currency":"USD"},{"qty":500,"price":"$4.84684","currency":"USD"},{"qty":1000,"price":"$4.42500","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/16389fg.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT1638IN8#PBF obsolete?","answer":"No. The lifecycle status is Active, with no last-time-buy or end-of-life notice issued."},{"question":"What packages are available for LT1638?","answer":"The LT1638IN8#PBF variant is in an 8-DIP through-hole package (0.300\" body width, 7.62 mm lead pitch), delivered in a tube.
