8 / 21 page  TMP006 TMP006B SBOS518C – MAY 2011 – REVISED DECEMBER 2012 www.ti.com INTERNAL REGISTERS The TMP006 and TMP006B contain data registers that hold configuration information, temperature measurement results, and status information.

POINTER REGISTER The TMP006 and TMP006B have 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 thermopile sensor voltage, VOBJECT. Table 3. Pointer Register (Write-Only) Register P7 P6 P5 P4 P3 P2 P1 P0 Reset value 0 0 0 0 0 0 0 0 SENSOR VOLTAGE REGISTER (VOBJECT) 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 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). Table 4.
