Product description
LP358AN - Dual, 32-V, 1-MHz, 2-mV offset voltage operational amplifier
Features for the LM358AN:
Available in 8-bump DSBGA chip-sized package (see AN-1112, SNVA009)
Internally frequency compensated for unity gain
Large DC voltage gain: 100 dB
Wide bandwidth (unity gain): 1 MHz (temperature compensated)
Wide power supply range:
Single supply: 3 V to 32 V
Or dual supplies: ±1.5 V to ±16 V
Very low supply current drain (500 µA) essentially independent of supply voltage
Low input offset voltage: 2 mV
Input common-mode voltage range includes ground
Differential input voltage range equal to the power supply voltage
Large output voltage swing
Unique characteristics:
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
The unity gain cross frequency is temperature compensated
The input bias current is also temperature compensated
Advantages:
Two internally compensated op amps
Eliminates need for dual supplies
Allows direct sensing near GND and VOUT also goes to GND
Compatible with all forms of logic
Power drain suitable for battery operation
Description for the LM358-N
The LM158 series 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 LM158 series can be directly operated off of the standard 3.3-V power supply voltage which is used in digital systems and will easily provide the required interface electronics without requiring the additional ±15-V power supplies.
