| L272 * L272A Dual Power Operational Amplifier June 2001 Revised May 2005 L272 * L272A Dual Power Operational Amplifier General Description 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. Features s Output Current up to 0.7A s Operates at Low Voltage (VS(MIN) = 4V) s Low Saturation Voltage (Ip = 0.5A, VO = 1.5V) s Thermal Shutdown (TSD = 160xC) Ground Compatible Inputs s Ground Compatible Inputs s Large Common Mode & Differential Mode Range Applications * Servo Amplifier * Power Supply * Compact Disc * VCR * Monitor Ordering Code: Product Number L272M L272D2 L272D2TF L272AM L272AD2 L272AD2TF Package 8-DIP 16-SOP 16-SOP 8-DIP 16-SOP 16-SOP Packing Tube Tube Tape and Reel Tube Tube Tape and Reel Operating Temperature 25qC to 85qC (c) 2005 Fairchild Semiconductor Corporation DS400471 www.fairchildsemi.com L272 * L272A Internal Block Diagram Pin Definitions Pin Number 8-DIP 1 2 3 4 5 6 7 8 16-SOP 16 1 2 4/5/12/13 7 8 9 10 Pin Name OUTPUT1 VCC OUTPUT2 VEE/GND INPUT2 INPUT2 INPUT1 INPUT1 Pin Function Description Amp Output 1 Positive Supply Voltage Amp Output 2 Negative Supply Voltage (GND) Amp Negative Input 2 Amp Positive Input 2 Amp Positive Input 1 Amp Negative Input 1 www.fairchildsemi.com 2 L272 * L272A Absolute Maximum Ratings(Note 1) Parameter Supply Voltage Input Voltage Differential Input Voltage DC Output Current Peak Output Current (Non Repetitive) Power Dissipation At: Tamb 50qC Operating Temperature Range Storage and Junction Temperature Symbol VCC VI VI(DIFF) IO IP Ptot Top Tstg, Tj Value 40 VS rVS Units V V V A A W 0.7 1 1 25 to 85 40 to 150 qC qC Thermal Data Parameter Thermal Resistance Junction-Ambient Maximum 8-DIP 16-SOP RTja 100 190 Symbol Value Unit qC/W Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed.
