You're mid-build, the circuit's got four channels to drive, and you need an op-amp that won't eat your battery. The LM324 does exactly that — four low-power operational amplifiers in one package, no extra board space, no power-hungry surprises. It's the workhorse IC that's been in every bench project since the '70s for a reason. Grab it, slot it in, and get back to wiring up the rest of the board
