POINTER REGISTER

The TMP006 has an 8-bit pointer used to address a given data register, as shown in Table 3. The pointer

identifies which of the data registers should respond to a read or write command on the two-wire bus. This

register is set with every write command. A write command must be issued to set the proper value in the pointer

before executing a read command. The power-on reset (POR) value of the pointer is 00h; this value selects the

The Sensor Voltage Register is a 16-bit result register in binary twos complement format. One least significant bit

(LSB) is 156.25 nV. The full-scale value is a

±5.12 mV signal. Data from this register (Table 4) are used in

conjunction with the data from the Temperature Register to calculate the object temperature. Table 4

summarizes the Sensor Voltage Register. The equation for the resultant object temperature is discussed in the

TMP006 User Guide (SBOU107).
