Same 4-amp layout as the dual LM358 above, just twice over: pin 4 is the one shared V+ for all four amps, pin 11 the one shared V−/GND — single-supply 3–32V, or dual-supply ±1.5–±16V.
The input stage does not handle signals near the negative rail cleanly: as the input common-mode voltage crosses near 0V/V− on a single supply, there is a well-documented crossover-distortion/phase-reversal region. Bias the input away from the rail (a mid-supply divider, for instance) if a clean signal near ground matters — this, combined with a modest ~0.4–0.5V/µs slew rate and ~1MHz gain-bandwidth, is why the LM324 is a poor pick for anything needing precision near 0V on a single rail.
