TECHNI CAL DATA Low Power Quad Operational Amplifier The IL324 contains four independent high gain operational amplifiers with internal frequency compensation. 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: 3V ~ 32V (or ±1.5V ~ ±16V) 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 LOGIC DIAGRAM IL324 ORDERING INFORMATION IL324N Plastic IL324D SOIC TA = -40° to +85° C for all packages.

However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this high-impedance circuit. For proper operation, VIN and VOUT 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 VCC). Unused outputs must be left open. 2011, January, ver.01 I L 324 DC ELECTRICAL CHARACTERISTICS (TA=-40 to +85°C) Guaranteed Limit Symbol VIO ∆VIO/∆T IIO ∆IIO/∆T IIB Parameter Test Conditions Maximum Input Offset Voltage VO=1.4V VCC=5.0-30V;RS=0Ω VICM=0V to VCC-1.7V Input Offset Voltage Drift RS=0Ω, VCC=30V Maximum Input Offset Current VCC=5.0V Typ Max Unit 9.0 mV 5.0* µV/°C 7.0 150 nA 50* Input Offset Current Drift RS=0Ω, VCC=30V Maximum Input Bias Current VCC=5.0V VICR Input Common Mode Voltage Range VCC=30V ICC Maximum Power Supply Current Minimum Large Signal Open-Loop Voltage Gain VCC=15V, RL≥2KΩ VOH Minimum Output HighLevel Voltage Swing VCC=30V,RL=2KΩ VCC=30V,RL=10KΩ VOL Maximum Output LowLevel Voltage Swing VCC=5V,RL=10KΩ AVOL Min 10 pA/°C 500 nA 250* 0 28 V RL=∞,VCC=30V,V0=0V 3 mA RL=∞,VCC=5V,V0=0V 1.2 V/mV 15 25* 26 27 V 20 mV CMR Common Mode Rejection VCC=30V, RS=10KΩ 65* dB PSR Power Supply Rejection VCC=30V 65* dB CS Channel Separation f=1KHz to 20KHz,VCC=30V -120* dB ISC Maximum Output Short Circuit to GND VCC=5.0V Isource Minimum Output Source Current VIN+=1V, VIN-=0V, VCC=15V, V0=0V 10 mA Minimum Output Sink Current VIN+=0V, VIN-=1V, VCC=15V, V0=15V VIN+=0V, VIN-=1V, VCC=15V, V0=0.2V 5 10* mA 12* µA Isink VIDR Differential Input Voltage Range All VIN≥GND or V-Supply (if used) 60* VCC* mA V *=@25°C 2011, January, ver.01 I L 324 TYPICAL PERFORMANCE CHARACTERISTICS Figure 1.Input Voltage Range Figure 3.
