UTC TS391/A LINEAR INTEGRATED CIRCUIT LOW POWER SINGLE VOLTAGE COMPARATOR DESCRIPTION The UTC TS391/A 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 a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage. 3 2 1 4 FEATURES 5 SOT-25 *Wide single supply voltage range or dual supplies +2V to *+34V 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.

This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference or input lines. 3.The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V.The upper end of the common-mode voltage range is Vcc+ -1.5V,but either or both inputs can go to +30V without damage. 4.Positive excursions of input voltage may exceed the 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 below the negative power supply, if used). 5.The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained. UTC UNISONIC TECHNOLOGIES CO.
