APPLICATIONS INFORMATION
After power-up, the ADC initiates an internal reset cycle
which sets the DIN word to all 0s (S/D=O/S=UNI=SLP=0).
A write operation may be performed if the default state
of the ADC’s conguration is not desired. Otherwise, the
ADC must be properly addressed and followed by a STOP
condition to initiate a conversion.
Initiating a New Conversion
The LTC2301/LTC2305 awakens from either nap or sleep
when properly addressed for a read/write operation. A
STOP command may then be issued after performing the
read/write operation to trigger a new conversion.
Issuing a STOP command after the 8th SCL clock pulse of
the address frame and before the completion of a read/write
operation will also initiate new conversion, but the output
result may not be valid due to lack of adequate acquisition
time (see Acquisition section).
LTC2301/LTC2305 Address
The LTC2301/LTC2305 have two address pins (AD0 and
AD1) that may be tied high, low or left oating to enable
one of the 9 possible addresses (see Table 2).
In addition to the congurable addresses listed in Table 2,
the LTC2301/LTC2305 also contain a global address
(1101011) which may be used for synchronizing multiple
LTC2301/LTC2305s or other I2C LTC230X SAR ADCs (see
Synchronizing Multiple LTC2301/LTC2305s with Global
Address Call section).

Continuous Read
In applications where the same input channel is sampled
each cycle, conversions can be continuously performed
and read without a write cycle (see Figure 8). The DIN word
remains unchanged from the last value written into the
device. If the device has not been written to since power-
up, the DIN word defaults to all 0s (S/D=O/S=UNI=SLP=0).
At the end of a read operation, a STOP condition may be
given to start a new conversion. At the conclusion of the
conversion cycle, the next result may be read using the
method described above. If the conversion cycle is not
concluded and a valid address selects the device, the
LTC2301/LTC2305 generates a NACK signal indicating the
conversion cycle is in progress.
