CM339 LOW POWER QUAD VOLTAGE COMPARATORS GENERAL DESCRIPTION FEATURES This device consists of four independent precision voltage ! devices: +2V to +36V or ± 1V to ± 18V comparators with an offset voltage specification as low as 2mV max for CM339. All these comparators were designed Wide single supply voltage range or dual supplies for all ! specifically to operate from a single power supply over a wide Very low supply current（1.1mA）independent of supply voltage（1.4mW/comparator +5V） range of voltages. Operation from split power supplies is also ! Low input bias current: 25nA typ possible. These Comparators also have a unique ! Low input offset current: ±5nA typ characteristic in that the input common mode voltage range ! Low input offset voltage: ±1mV typ includes ground even though operated from a single power ! Input common-mode voltage range includes ground supply voltage. ! Low output saturation voltage : 250mV typ,（Io = 4mA） ! Differential input voltage range equal to the supply voltage !

For larger overdrive signals 300ns can be obtained. 4.Positive excursions of input voltage may power supply level. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3V（or 0.3V bellow the negative power supply, if used）. 2001/07/02 Preliminary Champion Microelectronic Corporation Page 3 CM339 LOW POWER QUAD VOLTAGE COMPARATORS TYPICAL CHARACTERISTICS Supply Current Input Current Output Saturation Voltage Response Time for Various Input Overdrives – Negative Transistors Response Time for Various Input Overdrives – Positive Transistors 2001/07/02 Preliminary Champion Microelectronic Corporation Page 4 CM339 LOW POWER QUAD VOLTAGE COMPARATORS PACKAGE DIMENSION 14-PIN PDIP (P14) PIN 1 ID θ θ 14-PIN SOP (S14) PIN 1 ID θ θ 2001/07/02 Preliminary Champion Microelectronic Corporation Page 5 CERAMIC/SURGE ABSORBER SHANGHAI,CHINA DIODES LAB HANGZHOU,CHINA CERAMIC/PZT SHINCHU,TAIWAN DC POWER LAB TAIPEI,TAIWAN
