LND358
Dual Operational Amplifiers
DATA
SHEET
GENERAL DESCRIPTION
• Wide power supply range: (Single
supply: 5V to 30V)(Dual supplies:
± 2.5V to ±15V)
• Very low supply current drain
(700µA) independent of supply
voltage.
• Input common-mode voltage
range includes ground
• Available in 8 pin SO/ Dip package
• Internally frequency compensated
for unity gain
• Large DC voltage gain(100dB)
• Wide bandwidth(unity gain)-
1MHz(temperature compensated)
FEATURES
The LND358 consists of two independent, high
gain, internally frequency compensated
operational amplifiers. They 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 voltages.
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.
The LND358 is available in an 8pin DIP/S0
package.
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
• Application areas: transducer
amplifiers, dc gain blocks and all the
conventional op amp circuits
