LM239 Quad Voltage Comparators

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.

Features of LM239

  • 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
