IL2904 Low Power Dual Operational Amplifier The IL2904 cont ains t wo i ndependent high gai n operat ional am plifiers 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 l ow power suppl y current drain, regardless of t he power supply voltage. The low power drain also m akes t he IL2904 a good choi ce for battery operation.

ORDERING INFORMATION

TA = -40° to 85° C for all packages. When your project calls for a t raditional op-amp function, now you can streamline y our desi gn wi th a si mple si ngle power suppl y. Use ordinary +5VDC common t o pract ically any di gital system or personal computer application, without requi ring an ext ra 15V power suppl y just t o have t he interface electronics you need. The IL2904 is a versatile, rugged wo rkhorse 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:
  • Input common-mode voltage range includes ground
  • Large output voltage swing: 0V DC to VCC-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) PIN ASSIGNMENT LOGIC DIAGRAM PIN 4 = GND PIN 8=VCC

RECOMMENDED OPERATING CONDITIONS Symbol Parameter Min Max Unit VCC DC Supply Voltage ±2.5 or 5.0 ±15 or V TA Operating Temperature, All Package Types -40 +85 °C This device contains protection circuitry to guard against damage due to high static voltages or electric fields. However, precautions m ust be taken to avoid applications of any voltage highe r than maximum rated voltages to this high-impedance ci rcuit. For proper operat ion, V IN and V OUT should be const rained t o t he range GND ≤(VIN or VOUT)≤VCC. Unused inputs must always be t ied to an appropri ate logic voltage level (e.g., ei ther GND or VCC). Unused outputs must be left open.
