L272 / L272A Dual Power Operational Amplifier November 2013 L272 / L272A Dual Power Operational Amplifier Features Description Output Current up to 0.7 A The L272 and L272A are high-power dual operational Operates at Low Voltage (V = 4 V) amplifiers provided in a MDIP 8-lead package. The oper- S(MIN) ational amplifier is designed for low-impedance loads Low Saturation Voltage (I = 0.5 A, V = 1.5 V) P O and delivers output current up to 0.7 A. The L272A offers Thermal Shutdown (TSD = 160C) tighter specifications for input bias current, input offset Ground-Compatible Inputs voltage, and input offset current. The L272 and L272A Large Common Mode & Differential Mode Range can be used in a wide range of applications, including power supply, VCR, monitor, servo amplifier, compact Applications disc, etc. Servo Amplifier MDIP 8L Power Supply Compact Disc VCR Monitor 1 Ordering Information Part Number Operating Temperature Range Top Mark Package Packing Method L272M L272M MDIP 8L Rail -40 to +85 C L272AM L272AM MDIP 8L Rail Block Diagram OUT1 IN 1- 1 8 - + V CC 2 7 IN 1+ OUT2 3 6 IN 2+ + - V /GND 5 EE 4 IN 2- (MDIP 8L) Figure 1.

The device may not function or be opera- ble above the recommended operating conditions and stressing the parts to these levels is not recommended. In addi- tion, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Values are at T = 25C unless otherwise noted.

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. Thermal Characteristics Values are at T = 25C unless otherwise noted.
