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.

SOT-25

FEATURES

*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.

1.At output switch point, Vo=1.4V,Rs=0Ω with Vcc from 5V to 30V and over the full input common-mode range(0V

to Vcc 1.5V).

2.The direction of the input current is out of the IC due to the PN P input stage. 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.
