CMOS Quad Rail to Rail Input and Output Operational Amplifier 		Click link to Download

Features

(Typical unless otherwise noted)

  • Rail-to-Rail Input Common-Mode Voltage Range (Guaranteed Over Temperature)
  • Rail-to-Rail Output Swing (within 20 mV of supply rail, 100 kOhm load)
  • Guaranteed 3V, 5V and 15V Performance
  • Excellent CMRR and PSRR: 82 dB
  • Ultra Low Input Current: 20 fA
  • High Voltage Gain (RL = 500 kOhm): 130 dB
  • Specified for 2 kOhm and 600Ohm loads

    • Description

    The LMC6484 provides a common-mode range that extends to both supply rails. This rail-to-rail performance combined with excellent accuracy, due to a high CMRR, makes it unique among rail-to-rail input amplifiers.

    It is ideal for systems, such as data acquisition, that require a large input signal range. The LMC6484 is also an excellent upgrade for circuits using limited common-mode range amplifiers such as the TLC274 and TLC279.

    Maximum dynamic signal range is assured in low voltage and single supply systems by the LMC6484's rail-to-rail output swing. The LMC6484's rail-to-rail output swing is guaranteed for loads down to 600Ohm.

    Guaranteed low voltage characteristics and low power dissipation make the LMC6484 especially well-suited for battery-operated systems.

    See the LMC6482 data sheet for a Dual CMOS operational amplifier with these same features.

    Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
