The LM2901EP consists of four independent precision voltage comparators with an offset voltage specification as low as 2 mV max for all four comparators. These were designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. This comparator also has a unique characteristic in that the input common-mode voltage range includes ground, even though operated from a single power supply voltage.

Application areas include limit comparators, simple analog to digital converters; pulse, squarewave and time delay generators; wide range VCO; MOS clock timers; multivibrators and high voltage digital logic gates. The LM2901EP was designed to directly interface with TTL and CMOS. When operated from both plus and minus power supplies, it will directly interface with MOS logic— where the low power drain of the LM2901EP is a distinct advantage over standard comparators.

ENHANCED PLASTIC

  • Extended Temperature Performance of −40°C to +85°C
  • Baseline Control - Single Fab & Assembly Site
  • Process Change Notification (PCN)
  • Qualification & Reliability Data
  • Solder (PbSn) Lead Finish is standard
  • Enhanced Diminishing Manufacturing Sources (DMS) Support
