KK2903

The KK2903 is designed as one kind of low power low offset voltage dual comparators.The KK2903 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.

Features of the KK2903 are:(1)single or split supply operation;(2)low input bias current;(3)low input offset current;(4)input common mode voltage range to Gnd;(5)low output saturation voltage;(6)TTL and CMOS compatible.And the absolute maximum ratings of the KK2903 can be summarized as:(1)power supply voltages:single supply:36 V,split supplies:±18 V;(2)input differential voltage range:36 V;(3)input common mode voltage range:-0.3 to VCC V;(4)output short circuit to ground:continuous;(5)input current,per pin:50 mA;(6)junction temperature plastic packages:150 °C;(7)storage temperature:-65 to +150 °C;(8)lead temperature,1mm from case for 10 seconds:260 °C;(9)power dissipation @TA=25°C plastic package:570W;(10)derate above 25°C:5.7 mW/°C.If you want to know more information such as the electrical characteristics about this part,please download the datasheet in www.seekic.com and www.chinaicmart.com .
