    LTC2380-16

    reinitialize the ADC. No conversions should be initiated
    until 20μs after a POR event to ensure the reinitialization
    period has ended. Any conversions initiated before this
    time will produce invalid results.
    TIMING AND CONTROL
    CNV Timing
    The LTC2380-16 conversion is controlled by CNV. A ris-
    ing edge on CNV will start a conversion and power up the
    LTC2380-16. Once a conversion has been initiated, it cannot
    be restarted until the conversion is complete. For optimum
    performance, CNV should be driven by a clean low jitter
    signal. Converter status is indicated by the BUSY output
    which remains high while the conversion is in progress.
    To ensure that no errors occur in the digitized results, any
    additional transitions on CNV should occur within 40ns
    from the start of the conversion or after the conversion
    has been completed. Once the conversion has completed,
    the LTC2380-16 powers down and begins acquiring the
    input signal.
    Internal Conversion Clock
    The LTC2380-16 has an internal clock that is trimmed to
    achieve a maximum conversion time of 322ns. With a min-
    imum acquisition time of 165ns, throughput performance
    of 2Msps is guaranteed without any external adjustments.
    Auto Power-Down
    The LTC2380-16 automatically powers down after a con-
    version has been completed and powers up once a new
    conversion is initiated on the rising edge of CNV. During
    power down, data from the last conversion can be clocked
    out. To minimize power dissipation during power down,
    disable SDO and turn off SCK. The auto power-down feature
    will reduce the power dissipation of the LTC2380-16 as
    the sampling frequency is reduced. Since power is con-
    sumed only during a conversion, the LTC2380-16 remains
    APPLICATIONS INFORMATION
    powered-down for a larger fraction of the conversion cycle
    (tCYC) at lower sample rates, thereby reducing the average
    power dissipation which scales with the sampling rate as
    shown in Figure 12.
    DIGITAL INTERFACE
    The LTC2380-16 has a serial digital interface. The flexible
    OVDD supply allows the LTC2380-16 to communicate with
    any digital logic operating between 1.8V and 5V, including
    2.5V and 3.3V systems.
    The serial output data is clocked out on the SDO pin when
    an external clock is applied to the SCK pin if SDO is enabled.
    Clocking out the data after the conversion will yield the
    best performance. With a shift clock frequency of at least
    100MHz, a 2Msps throughput is still achieved. The serial
    output data changes state on the rising edge of SCK and
    can be captured on the falling edge or next rising edge of
    SCK. D15 remains valid till the first rising edge of SCK.
    The serial interface on the LTC2380-16 is simple and
    straightforward to use. The following sections describe the
    operation of the LTC2380-16. Several modes are provided
    depending on whether a single or multiple ADCs share the
    SPI bus or are daisy chained.
