STMicroelectronics | LM239ADT

The LM239ADT device 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.

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
