DS4000

DIGITAL TEMPERATURE SENSOR

The digital temperature sensor provides 10-bit temperature readings that indicate the temperature of the

device. Temperature readings are communicated from the DS4000 over a 2-wire serial interface. No

additional components are required. The DS4000 has an external address bit that allows a user to choose

the slave address from two possible values.

The factory-calibrated temperature sensor requires no external components. Upon power-up, the DS4000

starts performing temperature conversions with a resolution of 10 bits (+0.25°C resolution). Following an

8-bit command protocol, temperature data can be read over the 2-wire interface. The host can periodically

read the value in the temperature register, which contains the last completed conversion. As conversions

are performed in the background, reading the temperature register does not affect the conversion in

progress.

Reading Temperature

The DS4000 measures temperature through the use of an on-chip temperature-measurement technique

with an operation range from 0°C to +70°C (commercial) or -40°C to +85°C (industrial). The device

performs continuous conversions with the most recent result being stored in the temperature register. The

digital temperature is retrieved from the temperature register using the READ TEMPERATURE

command, as described in detail in the following paragraphs.

Table 2 shows the exact relationship of output data to measured temperature. The data is transmitted

serially over the 2-wire serial interface, MSB first. The MSB of the temperature register contains the

“sign” (S) bit, denoting whether the temperature is positive or negative. For Fahrenheit usage, a lookup

table or conversion routine must be used.

Note: Internal power dissipation raises the temperature above the ambient. The delta between ambient and the die temperature depends on

power consumption, PC board layout, and airflow.
