The LT1638IN8#PBF is a dual general-purpose op-amp from Linear Technology, packaged in an 8-pin DIP for through-hole assembly. 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.
