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 = 160°C) Ground Compatible Inputs Large Common Mode & Differential Mode Range
