L272AD2TF

Overview

The L272AD2TF is a dual power operational amplifier manufactured by onsemi (formerly Fairchild Semiconductor). It provides an output current up to 0.7A and operates at low voltages with a minimum supply voltage of 4V. The device features thermal shutdown protection triggered at 160°C, ground-compatible inputs, and a large common-mode and differential-mode voltage range. It is housed in a 16-SOP package.

Feature Summary

• Integrated thermal shutdown protection for overtemperature safety
• Ground-compatible input configuration simplifies circuit design
• Capable of delivering high output current for low impedance loads

Applications

• Servo amplifiers
• Power supplies
• Compact disc players
• Video cassette recorders
• Monitor circuits

Procurement Notes

Verify the manufacturer origin as onsemi or its predecessor Fairchild Semiconductor. Confirm the specific suffix 'TF' indicates tape and reel packaging within the 16-SOP format. Ensure the component matches the L272A variant specifications regarding tighter input bias and offset parameters if required by the design.

Selection Notes

Select this component when high output current capability near 0.7A is necessary for driving low impedance loads. The L272A variant offers improved input bias current and offset voltage characteristics compared to the standard L272. Consider the 16-SOP package dimensions and thermal resistance values for adequate heat dissipation in the final assembly.

Part Context

This part belongs to the L272/L272A family of dual power operational amplifiers designed for applications requiring significant output drive capabilities. The L272A designation signifies tighter electrical specifications for input parameters. The device is intended for use in consumer electronics and industrial control systems where robust power amplification is needed.
