TECHNICAL DATA
IL2904
Low Power Dual Operational Amplifier
The IL2904 contains two independent high gain operational amplifiers
with internal frequency compensation. The two op-amps operate over a wide
voltage range from a single power supply. Also use a split power supply. The
device has low power supply current drain, regardless of the power supply
voltage. The low power drain also makes the IL2904 a good choice for
battery operation.

to 85 C for all packages.
When your project calls for a traditional op-amp function, now you can
streamline your design with a simple single power supply. Use ordinary
+5V
DC
common to practically any digital system or personal computer
application, without requiring an extra 15V power supply just to have the
interface electronics you need.
The IL2904 is a versatile, rugged workhorse with a thousand-and-one
uses, from amplifying signals from a variety of transducers to dc gain blocks,
or any op-amp function. The attached pages offer some recipes that will have
your project cooking in no time.
Internally frequency compensated for unity gain
Large DC voltage gain: 100dB
Wide power supply range:
3V ~ 32V (or
1.5V ~ 16V)
Input common-mode voltage range includes ground
Large output voltage swing: 0V DC to V
CC
-1.5V DC
Power drain suitable for battery operation
Low input offset voltage and offset current
Differential input voltage range equal to the power supply voltage
Possible to exchange the position of Pin9 for Pin1 because of Pin
Connection being symmetric(IL2904S only)

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, V

should be constrained to the range GND

Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V

). Unused
outputs must be left open.
