L272M – STMicroelectronics

The STMicroelectronics L272M is a low-power dual operational amplifier specifically optimized for single-supply operation in automotive and industrial applications. Its key feature is a rail-to-rail output swing, maximizing dynamic range even with limited supply voltages. The L272M offers excellent input offset voltage stability across its operating temperature range of –40°C to 125°C. Each amplifier within the package can source or sink up to 40mA, providing ample drive capability for various loads. The device is commonly available in a space-saving 8-pin SOIC SMD package. It is frequently employed in sensor signal conditioning, active filtering, and low-side current sensing circuits where minimal power consumption and board space are critical. The L272M’s robust design and low quiescent current (typically 800uA per amplifier) make it ideal for battery-powered systems or applications with stringent power budgets. Its rail-to-rail output with 2.5V to 36V supply voltage is a distinct advantage for wide voltage ranges.
