7.6.2 Temperature Register

The Temperature Register of the TMP103 device is configured as an eight-bit, read-only register that stores the output of the most recent conversion. A single byte must be read to obtain data, and is described in Table 5. The data format for temperature is summarized in Table 6. One LSB equals 1°C.

Table 5. Temperature Register

D7 D6 D5 D4 D3 D2 D1 D0
T7 T6 T5 T4 T3 T2 T1 T0

Negative numbers are represented in binary twos complement format. Following power up or reset, the Temperature Register reads 0°C until the first conversion is complete.

Table 6. 8-Bit Temperature Data Format(1)

TEMPERATURE (°C) DIGITAL OUTPUT (BINARY) HEX
128 0111 1111 7F
127 0111 1111 7F
100 0110 0100 64
80 0101 0000 50
75 0100 1011 4B
50 0011 0010 32
25 0001 1001 19
0 0000 0000 00
–1 1111 1111 FF
–25 1110 0111 E7
–55 1100 1001 C9
(1) The resolution for the ADC is 1°C/count, where count is equal to the digital output of the ADC.

For positive temperatures (for example, 50°C):

Twos complement is not performed on positive numbers. Therefore, simply convert the number to binary code, left-justified format. Denote a positive number with MSB = 0.

Example: (50°C)/(1°C/count) = 50 = 32h = 0011 0010

For negative temperatures (for example, –25°C):

Generate the twos complement of a negative number by complementing the absolute value binary number and adding 1. Denote a negative number with MSB = 1.

Example: (|–25°C|)/(1°C/count) = 25 = 19h = 0001 1001

Twos complement format: 1110 0110 + 1 = 1110 0111
