RT2903H:Low power dual voltage comparator

This device consists of two independent low-power voltage comparators designed specifically to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible.

These comparators also have a unique characteristic in that the input common-mode voltage range includes ground even though operated from a single power supply voltage.

Key Features

  • Wide single supply voltage range or dual supplies: 2 V to 36 V or ±1 V to ±18 V
  • Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at 5 V)
  • Low input bias current: 25 nA typ.
  • Low input offset current: ±5 nA typ.
  • Input common-mode voltage range includes ground
  • Low output saturation voltage: 250 mV typ. (IO = 4 mA)
  • Differential input voltage range equal to the supply voltage
  • TTL, DTL, ECL, MOS, CMOS compatible outputs
  • Intended for use in aerospace and defense applications:
    • Dedicated traceability and part marking
    • Approval documents available for production parts
    • Adapted extended life time and obsolescence management
    • Extended product change notification process
    • Designed and manufactured to meet sub ppm quality goals
    • Advanced mold and frame designs for superior resilience to harsh environments (acceleration, EMI, thermal, humidity)
    • Extended screening capability on request
    • Single fabrication, assembly, and test site
    • Temperature range (-40 °C to 150 °C)
