LOW POWER QUAD VOLTAGE COMPARATORS 2001/07/02 Preliminary Champion Microelectronic Corporation Page 1 GENERAL DESCRIPTION

FEATURES

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

The upper and of the common-mode voltage range is Vcc + -1.5V, but either or both inputs can go to +30V without damage. 3.The response time specified is for a 100mV input step with 5mV overdrive. 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）.
