TEMPERATURE MEASURING CIRCUITRY Figure 4
Internally, this calculation is performed by the DS1624 to provide 0.03125
°C resolution. The temperature
reading is provided in a 13–bit, two’s complement reading by issuing READ TEMPERATURE
command. Table 2 describes the exact relationship of output data to measured temperature. The data is
transmitted serially through the 2–wire serial interface, MSB first. The DS1624 can measure temperature
over the range of -55
°C to +125°C in 0.03125°C increments. For Fahrenheit usage a lookup table or
conversion factor must be used.

Since data is transmitted over the 2–wire bus MSB first, temperature data may be written to/read from the
DS1624 as either a single byte (with temperature resolution of 1
°C) or as two bytes, the second byte
containing the value of the 5 least significant bits of the temperature reading as shown in Table 1. Note
that the remaining three bits of this byte are set to all 0’s.
