Overview
LM139, LM239, LM339 Low-power quad voltage comparators D SO14 (plastic micropackage) P TSSOP14 (thin shrink small outline package) Q QFN16 3x3 (plastic micropackage) Datasheet - production data Features • Wide single supply voltage range or dual supplies for all devices: +2 to +36 V or ±1 V to ±18 V • Very low supply current (1.
1 mA) independent of supply voltage • Low input bias current: 25 nA typ • Low input offset current: ±5 nA typ • Low input offset voltage: ±1 mV typ • Input common-mode voltage range includes ground • Low output saturation voltage: 250 mV typ; (ISINK = 4 mA) • Differential input voltage range equal to the supply voltage • TTL, DTL, ECL, MOS, CMOS compatible outputs Description This family of devices consists of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV maximum for LM339A, LM239A, and LM139A.
Each comparator has been 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.
