Product details

The LT1638IN8#PBF is a dual general-purpose op-amp from Linear Technology, packaged in an 8-pin DIP for through-hole assembly. Gain bandwidth product is 1.2 MHz and slew rate is 0.4 V/µs. Each output can source or sink 40 mA.

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.

No last-time-buy window is announced, and no official successor has been designated.

Frequently asked questions

Is LT1638IN8#PBF obsolete?

No. The lifecycle status is Active, with no last-time-buy or end-of-life notice issued.

What packages are available for LT1638?

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. Other package options for the LT1638 family include surface-mount SOIC and MSOP versions, but those are separate order codes.

What is the closest functional second-source for LT1638IN8#PBF?

The ADA4691-2ACPZ-R7 from Analog Devices is a dual rail-to-rail op-amp with a similar supply range (2.7 V to 5.5 V) and higher bandwidth (3.6 MHz), but it is surface-mount only and lacks the wide 44 V supply of the LT1638. For a true wide-supply dual in DIP, no pin-compatible second-source exists; the LT1638 is the standard choice in that footprint.
