LM2902N/D
QUAD OPERATIONAL AMPLIFIER
DESCRIPTION
The
LM2902
consist of four independent,
high gain, internally frequency compensated
operational amplifiers which were designed
specifically to operate from a single power
supply over a wide voltage range. 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
amplifier, DC gain
blocks and all the
DIP14
Outline Drawing
LM2902
LM2902N
conventional OP amp circuits which now can
be easily implemented in single power
supply systems.
LM2902D
FEATURE
Larg e DC voltage gain: 100dB
Wide power supply range:
Vcc=3V~32V(or Vcc=±1.5V~±1 6 V)
Input common-mode voltage range includes ground.
Large output voltage swing :0V~Vcc-1.5V
Power drain suitable for battery operation
Internally frequency compensated for unity gain
Wide bandwidth(unity gain) 1MHz
Very low supply current drain(700µA)—essentially independent of supply voltage
Low input biasing current
Low input offset voltage
45nA
2mV and offset current
5nA
SOP1 4
Differential input voltage range equal to the power supply voltage
Compatible with all forms of logic
