What the OP493EP is and where it fits
The Analog Devices OP493EP is a quad general-purpose operational amplifier in a 14-pin DIP package — through-hole, 0.300" wide body. It runs on a single supply from 2 V to 36 V or a split supply, draws just 14.5 µA total for all four channels, and swings rail-to-rail on the output. With a 35 kHz gain-bandwidth product and a 12 V/µs slew rate, this is a micropower part built for slow signals: sensor conditioning, battery monitoring, low-speed filtering, and industrial setpoint loops where the signal changes in milliseconds, not microseconds. The -40°C to 125°C temperature range means it works in an engine bay or a rooftop solar combiner box, not just a climate-controlled rack.
Key ratings and what they mean for the BOM
The 35 kHz gain-bandwidth product and 12 V/µs slew rate suit low-frequency signal conditioning. The 125 µV input offset and 20 nA bias current are typical for a general-purpose bipolar op-amp.
Package and mounting — through-hole still has a place
The OP493EP comes in a 14-lead PDIP (0.300" body, 7.62 mm pitch). Through-hole mounting allows socketing for easy replacement.
