LM139, LM239, LM339 Low-power quad voltage comparators 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 D Very low supply current (1.1 mA) independent SO14 of supply voltage (plastic micropackage) 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 P Low output saturation voltage: 250 mV typ TSSOP14 (I = 4 mA) SINK (thin shrink small outline package) Differential input voltage range equal to the supply voltage TTL, DTL, ECL, MOS, CMOS compatible outputs Q Description QFN16 3x3 This family of devices consists of four (plastic micropackage) 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.
