Features & Applications

The LM239PT is a 32 V supply voltage and 250 nA bias current low power quad voltage comparator, available in surface mount TSSOP-14 package.

This product consist of four independent precision-voltage comparators with an offset voltage specification as low as 2 mV. Each comparator has been designed specifically to operate from a single power supply over a wide range of voltages.

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
