| TECHNICAL DATA Low Power Quad Operational Amplifier The IL2902 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 IL2902 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 IL2902 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 IL2902 ORDERING INFORMATION IL2902N Plastic IL2902D SOIC TA = -40 to +85 C for all packages.

Split Power Supplies. 2. VIN<-0.3V. This input current will only exist when voltage at any of the input leads is driven negative. RECOMMENDED OPERATING CONDITIONS Symbol VCC TA DC Supply Voltage Operating Temperature, All Package Types Parameter Min 2.5 or 5.0 -40 Max 15 or 30 +85 Unit V 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 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. 2 IL2902 DC ELECTRICAL CHARACTERISTICS (TA=-40 to +85C) Guaranteed Limit Symbol VIO VIO/T IIO IIO/T IIB VICR ICC AVOL VOH VOL CMR PSR CS ISC Isource Isink Parameter Maximum Input Offset Voltage Input Offset Voltage Drift Maximum Input Offset Current Input Offset Current Drift Maximum Input Bias Current Input Common Mode Voltage Range Maximum Power Supply Current Test Conditions VO=1.4V VCC=5.0-30V;RS=0 VICM=0V to VCC-1.7V RS=0, VCC=30V VCC=5.0V RS=0, VCC=30V VCC=5.0V VCC=30V RL=,VCC=30V,V0=0V RL=,VCC=5V,V0=0V 15 25* 26 27 20 65* 65* -120* 60* 10 5 10* 12* VCC* V mV dB dB dB mA mA mA A V 0 10 500 250* 28 3 1.2 V/mV V mA 7.0 150 50* pA/C nA Min Typ Max 9.0 5.0* V/C nA Unit mV Minimum Large Signal VCC=15V, RL2K Open-Loop Voltage Gain Minimum Output HighLevel Voltage Swing Maximum Output LowLevel Voltage Swing Common Mode Rejection Power Supply Rejection Channel Separation Maximum Output Short Circuit to GND Minimum Output Source Current Minimum Output Sink Current VCC=30V,RL=2K VCC=30V,RL=10K VCC=5V,RL=10K VCC=30V, RS=10K VCC=30V f=1KHz to 20KHz,VCC=30V VCC=5.0V VIN+=1V, VIN-=0V, VCC=15V, V0=0V VIN+=0V, VIN-=1V, VCC=15V, V0=15V VIN+=0V, VIN-=1V, VCC=15V, V0=0.2V All VINGND or V-Supply (if used) VIDR *=@25C Differential Input Voltage Range 3 IL2902 TYPICAL PERFORMANCE CHARACTERISTICS Figure 1.Input Voltage Range Figure 2.
