UTL331 UTL331A Datasheet

LOW POWER SINGLE VOLTAGE COMPARATOR
 


 
DESCRIPTION

 
The UTC UTL331/A consists of a low power voltage comparator designed specifically for operation 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 that the input common-mode voltage range includes ground even though it is operated from a single power supply voltage.

 
 
FEATURES
 
 
* Wide single supply voltage range or dual supplies +2V~+36V or ±1V~±18V
* Very low supply current (0.2mA) independent of supply voltage (1mW /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.(IOUT=4mA).
* Differential input voltage range equal to the supply voltage.
*TTL, DTL, ECL, CMOS Compatible outputs.
