Data Transferring
After the START condition, the I2C bus is busy and data
transfer can begin between the master and the addressed
slave. Data is transferred over the bus in groups of nine
bits, one byte followed by one acknowledge (ACK) bit. The
master releases the SDA line during the ninth SCL clock
cycle. The slave device can issue an ACK by pulling SDA
LOW or issue a not-acknowledge (NACK) by leaving the
SDA line high impedance (the external pull-up resistor will
hold the line high). Change of data only occurs while the
clock line (SCL) is low.
Data Format
After a START condition, the master sends a 7-bit address
(factory set at 0010100), followed by a read request (R)
or write request (W) bit. The bit R is 1 for a read request
and 0 for a write request. If the 7-bit address agrees with
the LTC2451’s address, the device is selected. When the
device is addressed during the conversion state, it does
not accept the request and issues a NACK by leaving the
SDA line high. If the conversion is complete, the LTC2451
issues an ACK by pulling the SDA line LOW.
The user can send one byte of data into the LTC2451 fol-
lowing a write request and an ACK. The sequence is shown
in Figure 3. The write sequence is used solely to set the
conversion speed. The default conversion speed is 60Hz.
The user can specify a 30Hz conversion speed by setting
the eighth bit (S30) = 1, or specify a 60Hz conversion
speed by setting the eighth bit (S30) = 0.
After a read request and an ACK, the LTC2451 can output
data, as shown in Figure 4. The data output stream is 16
bits long and is shifted out on the falling edges of SCL.
