TECHNI CAL DATA Low Power Low Offset Voltage Dual Comparators 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 IL2903 ORDERING INFORMATION IL2903N Plastic IL2903D SOIC TA = -40° to 85° C for all packages.

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. 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 Parameter VCC DC Supply Voltage TA Operating Temperature, All Package Types Min Max Unit ±2.5 or 5.0 ±15 or 30 V -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 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 2903 DC ELECTRICAL CHARACTERISTICS (TA=-40 to +85°C) Guaranteed Limit Symbol Parameter VIO Input Offset Voltage Test Conditions Min V0=1.4V VCC=5.0-30V;RS≤100Ω VICR=0V - (VCC-1.5)V - Typ Max Unit 9.0 mV 5.0* IIB Input Bias Current V0=1.4V VCC=5.0-30V VICR=0V - (VCC-1.5)V - 400 nA IIO Input Offset Current V0=1.4V VCC=5.0-30V VICR=0V - (VCC-1.5)V - ±150 nA 50* VICR Input Common Mode Voltage Range VCC=5.0-30V 0 VCC2.0V V ICC Supply Current RL=∞,VCC=5.0 - 1.0* mA RL=∞,VCC=30V - 2.5* Voltage Gain VCC=15V, RL=15KΩ - 200* - V/mV t1 Large Signal Response Time VIN=TTL Logic Swing, Vref=1.4V, VCC=5.0V, RL=5.1KΩ, VRL=5.0V - 300* - ns t2 Response Time (Note 6) VCC=5.0V, RL=5.1KΩ, VRL=5.0V - 1.3* - µs Isink Output Sink Current VI(-)=1.0V, VI(+)=0V, V0≤1.5V, VCC=5.0V 6.0* - - mA Vsat Saturation Voltage VI(-)=1.0V, VI(+)=0V, Isink≤4.0mA, VCC=5.0V - - 700 mV IOL Output Leakage Current VI(+)=1.0V, VI(-)=0V, V0=5.0V V0=30V AVOL VIDR Differential Input Voltage Range All VIN≥GND or V-Supply (if used) nA 0.1* 1000 VCC V *=@25°C 2011, January, ver.01 I L 2903 TYPICAL PERFORMANCE CHARACTERISTICS (VCC=1.5V, TA=+25°C, (each comporator)) Figure 1.
