Overview
The LM324DTBG is a part of the LM324 series, which are low-cost, quad operational amplifiers (op-amps) designed by onsemi. These op-amps feature true differential inputs and are particularly advantageous in single supply applications. They can operate over a wide range of supply voltages, from 3.0 V to 32 V, with quiescent currents significantly lower than those of the MC1741. This makes them highly versatile and efficient for various electronic circuits.
