TS391 LOW POWER SINGLE VOLTAGE COMPARATORS . . .. .. . . . WIDE SINGLE SUPPLY VOLTAGE RANGE OR DUAL SUPPLIES +2V TO +36V OR ±1V TO ±18V VERY LOW SUPPLY CURRENT (0.2mA) INDEPENDENT OF SUPPLY VOLTAGE (1 mW/comparator at +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 OUTPUTS DESCRIPTION These devices consist of a low power voltage comparator designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground eventhough operatedfrom a single power supply voltage.

T he direction of the input cur rent is out of the IC due t o the PNP input stage. This cur rent is essenti ally constant, i ndependent of the state of the output, so no loading charge exists on the reference or input l ines. 4. T he input common-mode voltage of either i nput signal volt age should not be allow ed to go negati ve by more than 0.3V. T he upper end of the common-mode voltage range i s VC C + –1.5V, but either or bot h inputs can go to +30V without damage. 5. T he response time specifi ed is for a 100mV input step wi th 5mV overdr ive. F or lar ger overdrive signals 300ns can be obtained. 6. Positive excursions of input volt age may exceed the power suppl y level. As long as the other voltage remains wit hin the common-mode range the comparat or wi ll provi de a proper output state.
