Description

The LM2903AQ series comparators consist of 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 LM2903AQ series comparators are designed to directly interface with TTL and CMOS.

The LM2903AQ dual devices are available in SO-8, MSOP-8 and TSSOP-8; all in industry standard pinouts.

Both use green mold compound and and have been qualified to AEC-Q100 Grade 1 and are Automotive Compliant supporting PPAPs.

Feature(s)

  • Wide Power Supply Range:
    • Single Supply: 2V to 36V
    • Dual Supplies: ±1.0V to ±18V
  • Very Low 0.9mA Supply Current – Independent of Supply Voltage
  • 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 Supply Voltage
  • Low Output Saturation Voltage:
    • 100mV at 4mA
  • Output Voltage Compatible with TTL, MOS and CMOS
  • Qualified to AEC-Q100 Grade 1
  • PPAP Capable

Application(s)

  • Automotive
