www.fairchildsemi.com L272/L272A Dual Power Operational Amplifier Features 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. 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 = 160C) Ground Compatible Inputs Large Common Mode & Differential Mode Range Applications * * * * * 8-DIP Servo Amplifier Power Supply Compact Disc VCR Monitor 1 16-SOP 1 Internal Block Diagram OUT1 1 8 + Vcc OUT2 2 7 6 3 VCC 1 16 OUT1 OUT2 2 15 NC NC 3 14 NC VEE/GND 4 13 GND GND 5 12 GND NC 6 11 NC IN2- 7 - - 10 IN1- IN2+ 8 + + 9 IN1+ IN 1- IN 1+ IN 2+ + VEE/GND 5 4 (8-DIP) IN 2- (16-SOP) Rev. 1.0.3 (c)2009 Fairchild Semiconductor Corporation DUAL POWER OPERATIONAL AMPLIFIER Pin Definitions Pin Number 8-DIP 16-SOP 1 16 Pin Name Pin Function Description OUTPUT1 Amp Output 1 2 1 VCC 3 2 OUTPUT2 Positive Supply Voltage Amp Output 2 4 4/5/12/13 VEE/GND Negative Supply Voltage (GND) 5 7 INPUT-2 Amp Negative Input 2 6 8 INPUT+2 Amp Positive Input 2 7 9 INPUT+1 Amp Positive Input 1 8 10 INPUT-1 Amp Negative Input 1 Absolute Maximum Ratings (Note1) Parameter Symbol Value Unit VCC 40 V VI VS V VI(DIFF) VS V DC Output Current IO 0.7 A Peak Output Current (Non Repetitive) IP 1 A Power Dissipation At: Tamb = 50C Ptot 1 W Operating Temperature Range Top -25 to 85 C Tstg, Tj -40 to 150 C Supply Voltage Input Voltage Differential Input Voltage Storage and Junction Temperature Note 1: The "Absolute Maximum Ratings" are those values beyond which the safety of the device cannot be guaranteed.
