The LM2901B consists of four independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. It is fully specified at 5 V and 36 V single supply voltage operation, however operation from dual power supplies is also possible.

The B-grade version of the LM2901 comparators offers an increased maximum operating voltage of 40 V and improved electrical characteristics.

 

Features

  • AEC-Q100 qualified
  • Wide single supply voltage range or dual supplies +2 V to +36 V or ±1 V to ±18 V
  • Very low supply current 1 mA (typ., all channels), essentially independent of supply voltage
  • Low input bias current: 20 nA typ.
  • Low input offset current: ±5 nA typ.
  • Input common-mode voltage range includes negative rail
  • Low output saturation voltage: 250 mV typ. (IO = 4 mA)
  • Input voltage range can exceed the positive supply voltage
  • TTL, DTL, ECL, MOS, CMOS compatible outputs

 

Applications

  • Level shifters
  • Sampling circuits
  • Peak & zero crossing detectors
  • Threshold detectors
  • Automotive
