and the device begins outputting data at time tEOCtest after
the falling edge of CS (if EOC = 0) or tEOCtest after EOC goes
LOW (if CS is LOW during the falling edge of EOC). The
value of tEOCtest is 23s if the device is using its internal
oscillator (F0 = logic LOW). If FO is driven by an external
oscillator of frequency fEOSC, then tEOCtest is 3.6/fEOSC. If
CS is pulled HIGH before time tEOCtest, the device returns
to the sleep state and the conversion result is held in the
internal static shift register.
If CS remains LOW longer than tEOCtest, the first rising
edge of SCK will occur and the conversion result is serially
shifted out of the SDO pin. The data output cycle concludes
after the 19th rising edge. Data is shifted out the SDO pin
on each falling edge of SCK. The internally generated serial
clock is output to the SCK pin. This signal may be used to
shift the conversion result into external circuitry. EOC can
be latched on the first rising edge of SCK and the last bit
of the conversion result on the 19th rising edge of SCK.
After the 19th rising edge, SDO goes HIGH (EOC = 1), SCK
stays HIGH and a new conversion starts.
Typically, CS remains LOW during the data output state.
However, the data output state may be aborted by pulling
CS HIGH anytime between the first and 19th rising edge of
SCK, see Figure 10. On the rising edge of CS, the device
aborts the data output state and immediately initiates a
new conversion. This is useful for aborting an invalid
conversion cycle, or synchronizing the start of a conver-
sion. If CS is pulled HIGH while the converter is driving
SCK LOW, the internal pull-up is not available to restore
SCK to a logic HIGH state. This will cause the device to exit
the internal serial clock mode on the next falling edge of
CS. This can be avoided by adding an external 10k pull-up
resistor to the SCK pin or by never pulling CS HIGH when
SCK is LOW.
Whenever SCK is LOW, the LTC2436-1’s internal pull-up
at pin SCK is disabled. Normally, SCK is not externally
driven if the device is in the internal SCK timing mode.
However, certain applications may require an external
driver on SCK. If this driver goes Hi-Z after outputting a
LOW signal, the LTC2436-1’s internal pull-up remains
