A fast, low-power general-purpose op amp in a through-hole package
Packaged in an 8-pin DIP (0.300" body, 7.62 mm pitch) for through-hole mounting, it targets breadboard prototyping, legacy system retrofits, and low-power signal conditioning where board space is not the primary constraint.
The AD518KN operates from a single 10 V supply (both minimum and maximum span are 10 V). It is specified over the -55°C to 70°C temperature range, which covers commercial and most industrial indoor environments but stops short of extended industrial or automotive under-hood conditions. For designs needing a wider temperature range, a different grade or package variant would be required.
What the slew rate and supply current mean for your design
The 70 V/µs slew rate is unusually high for a general-purpose op amp running on only 5 µA supply current. This combination suits applications that need fast edge response — such as pulse amplifiers, waveform generators, or high-speed comparator front ends — without burning the power budget of a typical high-speed op amp. The 12 MHz gain-bandwidth product supports closed-loop gains up to about 10 at 1 MHz before the open-loop rolloff limits accuracy. The 2 mV input offset is moderate; designs requiring better than 0.1% DC accuracy at low gains may need an external trim or a precision op amp.
Active lifecycle and RoHS status
Note that it is RoHS non-compliant, which may restrict its use in regions requiring lead-free assembly. For RoHS-compliant builds, a surface-mount alternative such as the ADA4004-1ARZ or AD8675ARMZ should be evaluated.
