LM324 is a quad operational amplifier designed by Unisonic Technologies Co., LTD. It can work in a wide voltage range from a single supply or from split power supplies. It is widely used in transducer amplifier, DC gain blocks and all the conventional OP amp circuits.
The UTC LM324 is a quad operational amplifier designed for single‑supply operation over a wide voltage range (3 V – 32 V) and also supports split supplies. It offers high DC voltage gain (100 dB), large output swing, low power drain for battery use, and includes internal frequency compensation for unity‑gain stability.
