    LTC1857/LTC1858/LTC1859
    8-Channel, 12-/14-/16-Bit,
    100ksps SoftSpan A/D Converters
    185789f
    with Shutdown
    The LTC
    1857/LTC1858/LTC1859 are 8-channel, low
    power, 12-/14-/16-bit, 100ksps, analog-to-digital con-
    verters (ADCs). These SoftSpan
    TM
     ADCs can be software-
    programmed for 0V to 5V, 0V to 10V, 
    ±
    5V or 
    ±
    10V input
    spans and operate from a single 5V supply. The 8-chan-
    nel multiplexer can be programmed for single-ended
    inputs or pairs of differential inputs or combinations of
    both. In addition, all channels are fault protected to 
    ±
    25V.
    A fault condition on any channel will not affect the
    conversion result of the selected channel.
    An onboard high performance sample-and-hold and pre-
    cision reference minimize external components. The low
    40mW power dissipation is made even more attractive
    with two user selectable power shutdown modes. DC speci-
    fications include 
    ±
    3LSB INL for the LTC1859, 
    ±
    1.5LSB
    INL for the LTC1858 and 
    ±
    1LSB for the LTC1857.
    The internal clock is trimmed for 5
    μ
    s maximum conver-
    sion time and the sampling rate is guaranteed at 100ksps.
    A separate convert start input and data ready signal (BUSY)
    ease connections to FIFOs, DSPs and microprocessors.
