LM2901 - DUAL AND QUAD DIFFERENTIAL COMPARATORS

General Description

The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification.

They are designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible.

Key Features

  • Wide Power Supply Range:.
  • Single Supply: 2V to 36V.
  • Dual Supplies: ±1.0V to ±18V.
  • Very Low Supply Current Drain.
  • Independent of Supply Voltage.
  • LM2903: 0.6mA.
  • LM2901: 0.9mA.
  • Low Input Bias Current: 25nA.
  • Low Input Offset Current: ±5nA.
  • Typical Offset Voltage:.
  • Non-A Device: 2mV.
  • A Device: 1mV.
  • Common-Mode Input Voltage Range Includes Ground.
  • Differential Input Voltage Range Equal to the Power Sup.

LM2901/ LM2901A/ LM2903/ LM2903A DUAL AND QUAD DIFFERENTIAL COMPARATORS Description The LM2901/2903 series comparators consist of four and two independent precision voltage comparators with very low input offset voltage specification. They are designed to operate from a single power supply over a wide range of voltages; however operation from split power supplies is also possible. They offer low power supply current independent of the magnitude of the power supply voltage. The LM2901/2903 series comparators are designed to directly interface with TTL and CMOS. When operating from both plus and minus power supplies, the LM2901/2903 series comparators will directly interface with MOS logic where their low power drain is a distinct advantage over standard comparators.
