SENSOR VOLTAGE FORMAT

The TMP006 provides 16 bits of data in binary twos complement format. The positive full-scale input produces an

output code of 7FFFh and the negative full-scale input produces an output code of 8000h. The output clips at

these codes for signals that exceed full-scale. Table 5 summarizes the ideal output codes for different input

signals. Figure 6 illustrates code transitions versus input voltage. Full-scale is a 5.12 mV signal. The LSB size is

156.25 nV.
