The LM324AD is a low-power quad operational amplifier from STMicroelectronics. It is designed to deliver high performance in a very small package and it is one of the smallest quad op amps in the industry. It is capable of providing extremely low power consumption and wide bandwidth, making it suitable for a variety of applications. The LM324AD is rated to operate over the -40°C to 85°C temperature range and has a 4MHz gain bandwidth product. The op amp also has a low input-bias and offset current, excellent ac and dc performance, and very fast slew rate. The LM324AD is also RoHS compliant and is offered in a compact 8-pin SO-8 package, making it an ideal choice for space-constrained applications such as medical equipment, appliances and wearables.
