L272D ST Operational Amplifier | 16-SO | Dual Channel, 1A Output

Product Overview

The L272D is a dual operational amplifier from STMicroelectronics, designed for high-current output applications. It features two independent op-amps capable of delivering up to 1A output current per channel, making it ideal for driving loads such as motors, valves, and audio speakers. The device operates from a single or dual supply voltage ranging from 4V to 28V, and is housed in a compact 16-SO package. With a wide common-mode input voltage range and low saturation voltage, the L272D offers excellent performance in industrial and automotive environments.
