Revised May 2005 L272 • L272A Dual Power Operational Amplifier General Description Features The L272 and L272A are high-power dual operational amplifier provided as a 8-DIP and 16-SOP package. The operational amplifier is designed for low impedance loads and will deliver output current up to 0.7A. The L272A offers tighter specifications for input bias current, input offset voltage and input offset currents. The L272 and L272A can be used in a wide range of applications including power supply, VCR, monitor, servo amplifier, compact disc, etc. ■ Output Current up to 0.7A ■ Operates at Low Voltage (VS(MIN) = 4V) ■ Low Saturation Voltage (Ip = 0.5A, VO = 1.5V) ■ Thermal Shutdown (TSD = 160×C) Ground Compatible Inputs ■ Ground Compatible Inputs ■ Large Common Mode & Differential Mode Range Applications • Servo Amplifier • Power Supply • Compact Disc • VCR • Monitor Ordering Code: Package Packing L272M Product Number 8-DIP Tube L272D2 16-SOP Tube L272D2TF 16-SOP Tape and Reel L272AM 8-DIP Tube L272AD2 16-SOP Tube L272AD2TF 16-SOP Tape and Reel © 2005 Fairchild Semiconductor Corporation Operating Temperature 25qC to 85qC DS400471 www.fairchildsemi.com L272 • L272A Dual Power Operational Amplifier June 2001 L272 • L272A Internal Block Diagram Pin Definitions Pin Number Pin Name Pin Function Description 8-DIP 16-SOP 1 16 OUTPUT1 2 1 VCC 3 2 OUTPUT2 Amp Output 2 4 4/5/12/13 VEE/GND Negative Supply Voltage (GND) 5 7 INPUT2 Amp Negative Input 2 6 8 INPUT2 Amp Positive Input 2 7 9 INPUT1 Amp Positive Input 1 8 10 INPUT1 Amp Negative Input 1 www.fairchildsemi.com 2 Amp Output 1 Positive Supply Voltage L272 • L272A Absolute Maximum Ratings(Note 1) Parameter Symbol Value VCC 40 V VI VS V V Supply Voltage Input Voltage Units VI(DIFF) ❏rVS DC Output Current IO 0.7 A Peak Output Current (Non Repetitive) IP 1 A Differential Input Voltage Power Dissipation At: Tamb 50qC Operating Temperature Range Storage and Junction Temperature Ptot 1 W Top 25 to 85 40 to 150 qC qC Tstg, Tj Thermal Data Parameter Symbol Value Unit RTja 100 qC/W Thermal Resistance Junction-Ambient Maximum 8-DIP 16-SOP 190 Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed.
