Overview
The L272 and L272A are high-power dual operational amplifiers provided in an MDIP 8-lead package. These amplifiers are designed for low-impedance loads and deliver output current up to 0.7 A. The L272A offers tighter specifications for input bias current, input offset voltage, and input offset current compared to the L272. Both models are suitable for a wide range of applications, including power supply, VCR, monitor, servo amplifier, and compact disc systems.
