LM324 Low Power Quad Op-Amp IC (SMD Package)

Four of the most commonly needed analog building blocks, signal amplification, comparison, filtering, buffering, often turn up together on the same board, which is exactly what the LM324 is built for, packing four independent op-amps into a single chip rather than reaching for four separate single-amp parts. This SMD-package version carries that same quad op-amp function onto a compact surface-mount footprint, meant for a finished PCB layout rather than the breadboard-friendly DIP-14 version already in the catalog.
