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 volt-age 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.

Pin Definitions

Absolute Maximum Ratings (Note1)

Note 1: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings.
