OPERATIONMEASURING TEMPERATURE
Figure 1 shows a block diagram of the DS1624. The DS1624 measures the temperature using a bandgap-
based temperature sensor. A delta-sigma analog-to-digital (ADC) converts the temperature to a 12-bit
digital value that is calibrated in 癈; for 癋 applications a lookup table or conversion routine must be
used. Throughout this data sheet the term conversion is used to refer to the entire temperature
measurement and ADC sequence.
The temperature reading is stored as a 16-bit twos complement number in the 2-byte temperature register
as shown in Figure 4.

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癈) or as 2 bytes, the second byte
containing the value of the four least significant bits of the temperature reading as shown in Figure 4.
Note that the remaining 4 bits of this byte are set to all zeros.
Temperature is represented in the DS1624 in terms of a 0.0625癈 LSB, yielding the following 12-bit
example:
Operation and Control
A configuration/status register is used to determine the method of operation of the DS1624 will use in a
particular application as well as indicating the status of the temperature conversion operation.
