    LTC2484
    24-Bit ∆Σ ADC with
    Easy Drive Input Current Cancellation
    Features Description Easy Drive Technology Enables Rail-to-Rail Inputs
    with Zero Differential Input Current
    n Directly Digitizes High Impedance Sensors with
    Full Accuracy
    n 600nV
    RMS Noise
    n GND to V
    CC Input/Reference Common Mode Range
    n Programmable 50Hz, 60Hz or Simultaneous 50Hz/60Hz Rejection Mode
    n 2ppm INL, No Missing Codes
    n 1ppm Offset and 15ppm Total Unadjusted Error
    n Selectable 2× Speed Mode (15Hz Using Internal
    Oscillator)
    n No Latency: Digital Filter Settles in a Single Cycle
    n Single Supply 2.7V to 5.5V Operatio Internal Oscillator
    n Available in a Tiny (3mm × 3mm) 10-Lead DFN Package The LTC®2484 combines a 24-bit No Latency ∆Σ™ analogto-digital converter with patented Easy Drive™ technology.
    The patented sampling scheme eliminates dynamic input
    current errors and the shortcomings of on-chip buffering
    through automatic cancellation of differential input current.
    This allows large external source impedances and input ...
