| TECHNICAL DATA Low Power Low Offset Voltage Dual Comparators IL2903 The IL2903 consists of two independent precision voltage comparators with an offset voltage specification as low as 2.0 mV max for two comparators which were designed specifically to operate from a single power supply over a wide range of voltages. Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. * * * * * * Single or Split Supply Operation Low Input Bias Current Low Input Offset Current Input Common Mode Voltage Range to Gnd Low Output Saturation Voltage TTL and CMOS Compatible ORDERING INFORMATION IL2903N Plastic IL2903D SOIC TA = -40 to 85 C for all packages.

Functional operation should be restricted to the Recommended Operating Conditions. Notes: 1. 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 IL2903 DC ELECTRICAL CHARACTERISTICS (TA=-40 to +85C) Guaranteed Limit Symbol VIO Parameter Input Offset Voltage Test Conditions V0=1.4V VCC=5.0-30V;RS100 VICR=0V - (VCC-1.5)V V0=1.4V VCC=5.0-30V VICR=0V - (VCC-1.5)V V0=1.4V VCC=5.0-30V VICR=0V - (VCC-1.5)V VCC=5.0-30V RL=,VCC=5.0 RL=,VCC=30V AVOL t1 Voltage Gain Large Signal Response Time Response Time (Note 6) Output Sink Current Saturation Voltage Output Leakage Current Differential Input Voltage Range VCC=15V, RL=15K VIN=TTL Logic Swing, Vref=1.4V, VCC=5.0V, RL=5.1K, VRL=5.0V VCC=5.0V, RL=5.1K, VRL=5.0V VI(-)=1.0V, VI(+)=0V, V01.5V, VCC=5.0V VI(-)=1.0V, VI(+)=0V, Isink4.0mA, VCC=5.0V VI(+)=1.0V, VI(-)=0V, V0=5.0V V0=30V All VINGND or V-Supply (if used) Min Typ Max 9.0 5.0* 400 nA Unit mV IIB Input Bias Current IIO Input Offset Current - 150 50* nA VICR ICC Input Common Mode Voltage Range Supply Current 0 200* 300* VCC2.0V 1.0* 2.5* - V mA V/mV ns t2 Isink Vsat IOL 6.0* - 1.3* - 700 s mA mV nA 0.1* 1000 VCC V VIDR *=@25C 3 IL2903 TYPICAL PERFORMANCE CHARACTERISTICS (VCC=1.5V, TA=+25C, (each comporator)) Figure 1.
