Single general-purpose op-amp with 5 MHz GBWP and rail-to-rail output
The MCP6281-E/P: The rail-to-rail output stage lets it swing close to the supply rails, which helps when driving an ADC input or a low-voltage load without losing headroom.
Through-hole DIP package — field-swappable, breadboard-friendly
Housed in an 8-pin DIP package (0.300" width, 7.62 mm pitch), the MCP6281-E/P is a through-hole part that fits standard breadboards and prototyping sockets, and it's easy to swap in the field with basic tools — no hot-air station needed. The supplier device package is 8-PDIP, and it ships in tube form — not tape-and-reel, so plan for manual placement or a tube feeder on the pick-and-place if you're running a through-hole line.
Temperature range and input characteristics for industrial use
Input bias current is a mere 1 pA (typical), which means it won't load down high-impedance sources like photodiode or pH probe outputs — the offset voltage is specified at 3 mV maximum, so plan for a trim or accept the DC error in your gain stage.
