DAC38J84: Temp. Sensor internal location

Temperature sensor is located near the die edge/corner adjacent to the DACs.

The temperature sensor outputs the temperature data in 8-bit, 2's complement format.

For example, 0 degree corresponds to b0000-0000, 25 degree corresponds to b0001-1001. The MSB indicates the positive or negative sign. For instance, -2 is represented by b1111- 1110.

To calculate the negative temperatures, first calculate the values as you would for any binary to decimal conversion, and then subtract the decimal from 2^8 or 256 (i.e. b1111-1110 = d254. 254-256 = -2 degrees).

If you have more questions, please feel free to let us know.

Hi,

The temp sensor is on the chip (die) itself, so it is reading the temperature of the die.

We don't have the details of your question since we do not have the designs.
