with the most significant bit of the result being present at
the SDO output pin (SDO = D15) once CS goes low. A new
data bit appears at the SDO output pin after each falling
edge detected at the SCK input pin. The output data can be
reliably latched by the user using the rising edge of SCK.
Conversion Status Monitor
For certain applications, the user may wish to monitor
the LTC2452 conversion status. This can be achieved
by holding SCK HIGH during the conversion cycle. In
this condition, whenever the CS input pin is pulled low
(CS = LOW), the SDO output pin will provide an indication
of the conversion status. SDO = HIGH is an indication of
a conversion cycle in progress while SDO = LOW is an
indication of a completed conversion cycle. An example
of such a sequence is shown in Figure 5.
Conversion status monitoring, while possible, is not re-
quiredforLTC2452asitsconversiontimeisfixedandequal
at approximately 16.6ms (23ms maximum). Therefore,

conversion cycle.
SERIAL INTERFACE
The LTC2452 transmits the conversion result and receives
the start of conversion command through a synchronous
3-wire interface. This interface can be used during the
CONVERT and SLEEP states to assess the conversion
status and during the DATA OUTPUT state to read the
conversion result, and to trigger a new conversion.
Serial Interface Operation Modes
The modes of operation can be summarized as follows:
1) The LTC2452 functions with SCK idle high (commonly
known as CPOL = 1) or idle low (commonly known as
CPOL = 0).
