General-purpose op-amp in a TO-99 can — what you are getting
The AD510KH is a single general-purpose operational amplifier from Analog Devices, housed in a TO-99-8 metal can package. It is a through-hole part — no hot-air station needed, just a socket or a soldering iron, which makes it a field-swappable candidate for bench instruments, lab supplies, and older PCB designs that still use the TO-99 footprint. The 50 µV input offset voltage and 13 nA input bias current give it decent DC precision for a general-purpose stage, and the supply span runs from 10 V to 36 V single or split rail, so it fits into ±5 V to ±18 V systems without a regulator tweak.
That means this part belongs in a lab, an office, or a controlled indoor environment — not in a motor drive cabinet or under a car hood. If your BOM calls for industrial or automotive temperature, you will need a different op-amp family.
That simplifies BOM planning for legacy designs that still specify this TO-99 op-amp.
Because the AD510KH is active but RoHS non-compliant, it is not stocked by every distributor.
