2011, January, ver.01 Low Power Quad Operational Amplifier The IL324 contains four independent high gain operational amplifiers with internal frequency compensati on. The four 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 IL324 a good choice for battery operation. When your project calls for a traditional op-amp function, now you can streamline your design with a simple single power supply. Use ordinary +5VDC 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 IL324 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:
  • 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 IL324

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Functional operation should be restricted to the Recommended Operating Conditions. +Derating - Plastic DIP: - 10 mW/°C from 65° to 125°C Notes: 1. Split Power Supplies. 2. V IN<-0.3V.

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 must be taken to avoid applications of any voltage higher than maximum rated voltag es to this high-impedance circuit. For proper operation, V IN and V OUT should be constrained to the range GND ≤(VIN or VOUT)≤VCC. Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V CC). Unused outputs must be left open.
