Wing LM358 Dual operation amplifier Datasheet

Dual Operation Amplifiers
LM358
General Description
Advantages
The LM358 consists of two independent, high gain, internally frequency compensated operational amplifiers which
were designed specifically to operate from a single power
supply over a wide range of voltages. Operation from split
power supplies is also possible and the low power supply
current drain is independent of the magnitude of the power
supply voltage.
Application areas include transducer amplifiers, dc gain
blocks and all the conventional op amp circuits which now
can be more easily implemented in single power supply systems. For example, the LM358 can be directly
operated off of the standard +5V power supply voltage which is
used in digital systems and will easily provide the required
interface electronics without requiring the additional ± 15V
power supplies.
n Two internally compensated op amps
n Eliminates need for dual supplies
n Allows direct sensing near GND and VOUT also goes to
GND
n Compatible with all forms of logic
n Power drain suitable for battery operation
n Pin-out same as LM1558/LM1458 dual op amp
Unique Characteristics
n In the linear mode the input common-mode voltage
range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage.
n The unity gain cross frequency is temperature
compensated.
n The input bias current is also temperature compensated.
Features
n Internally frequency compensated for unity gain
n Large dc voltage gain: 100 dB
n Wide bandwidth (unity gain): 1 MHz
(temperature compensated)
n Wide power supply range:
— Single supply: 3V to 32V
— or dual supplies: ± 1.5V to ± 16V
n Very low supply current drain (500 µA) — essentially
independent of supply voltage
n Low input offset voltage: 2 mV
n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power
supply voltage
n Large output voltage swing: 0V to V+− 1.5V
