1 LM358 LOW POWER DUAL OPERATIONAL AMPLIFIERS LM358 Document number: DS35167 Rev. 2 - 2 1 of 14 February 2011 Diodes Incorporated NEW PRODUCT Description The LM358 series consists of two independent, high gain,internally frequency compensated operational amplifierswhich were designed specifically to operate from a singlepower supply over a wide range of voltages. Operation fromsplit power supplies is also possible and the low powersupply current drain is independent of the magnitude of thepower supply voltage . Application areas include transducer amplifiers, dc gainblocks and all the conventional op amp circuits which nowcan be more easily implemented in single power supplysystems.

2 For example, the LM358 series can be directlyoperated from the standard +5V power supply voltage whichis used in digital systems and will easily provide the requiredinterface electronics without requiring an additional 15 Vpower supply. Features Internally frequency compensated for unity gain Large dc voltage gain: 100 dB Very low supply current drain (500 A); essentially independent of supply voltage Wide bandwidth (unity gain): 1 MHz (temperature compensated) Input common-mode voltage range includes ground Differential input voltage range equal to the power supply voltage Low input offset voltage : 2mV Wide power supply range: o Single supply: 3V to 32V o Dual supplies: to 16V Large output voltage swing.

3 0V to V+ - SOP-8L packaging Green Molding Compound (No Br, Sb) Lead Free Finish/ RoHS Compliant (Note 1) Pin Assignments Applications Eliminates the need for dual supplies Compatible with all forms of logic Two internally compensated op amps Low power drain ideal for battery operation Allows direct sensing near GND VOUT can swing to GND Unique Characteristics In the linear mode the input common-mode voltage range includes ground and the output voltage can also swing to ground, whilst operating from only a single power supply voltage . The unity gain crossing frequency is temperature compensated. The input bias current is temperature compensated. Notes: 1.
