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 volt-
age and input offset currents. The L272 and L272A can be
used in a wide range of applications including power sup-
ply, VCR, monitor, servo amplifier, compact disc, etc.

Absolute Maximum Ratings
(Note 1)
Thermal Data
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.
