L272M

Overview

The L272M is a dual operational amplifier manufactured by onsemi, housed in an 8-pin PDIP package for through-hole installation. It supports single or dual power supplies, with typical single supply voltages ranging from 5V to 24V and dual supplies including ±3V, ±5V, ±9V, and ±12V. The device features a gain-bandwidth product of 350kHz and a typical slew rate of 1V/µs. Key electrical parameters include a typical voltage gain of 75dB, input offset voltage of 60mV, and input bias current of 2.5µA. It operates within a temperature range of -25°C to +85°C.

Procurement Notes

Verify the specific manufacturer part number against official onsemi documentation to ensure authenticity. Confirm that the component matches the required DIP-8 package and through-hole mounting specifications. Check for any obsolescence notices or lifecycle status changes directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when a dual operational amplifier with moderate bandwidth and low cost is required. Ensure the application voltage stays within the specified 4V to 28V range. Consider the 1V/µs slew rate and 350kHz gain-bandwidth product for signal integrity requirements. Verify that the non-rail-to-rail output swing meets the system's dynamic range needs.

Part Context

The L272M belongs to the L272 series of dual operational amplifiers produced by onsemi. This series utilizes CMOS technology to balance power consumption and performance. The component is designed for general-purpose applications where cost-effectiveness and standard packaging are prioritized over high-speed precision characteristics.

Replacement Considerations

Consult official onsemi substitution guides for verified equivalents. Cross-reference pinouts and electrical specifications carefully if considering alternatives from other manufacturers.
