OPERATION
Measuring Temperature
A block diagram of the DS1621 is shown in Figure 1.
 
The DS1621 measures temperature using a bandgap-based temperature sensor. A delta-sigma analog-to-
digital converter (ADC) converts the measured temperature to a digital value that is calibrated in 癈; for
癋 applications, a lookup table or conversion routine must be used.
 
The temperature reading is provided in a 9-bit, twos complement reading by issuing the READ
TEMPERATURE command. Table 2 describes the exact relationship of output data to measured
temperature. The data is transmitted through the 2-wire serial interface, MSB first. The DS1621 can
measure temperature over the range of -55癈 to +125癈 in 0.5癈 increments.
