8.4 Device Functional Modes

The TMP006 and TMP006B operate in two modes: continuous and shutdown. A software reset function is also

available. Selecting the desired operating mode is done by writing to the configuration register conversion mode

select bits MOD[2:0]. The duration of the analog-to-digital (A/D) conversion is determined by the conversion rate

bits CR[2:0] and is listed in Table 7. Continuous mode, on the other hand, performs an A/D conversion followed

by a low-power delay in order to reduce the average power consumption. Multiple options for the conversion time

and delay time are available in order to select the desired power and noise performance. Initiating power-down

has an immediate effect; it aborts the current conversion and puts the device into a low-power shutdown mode.

RST, or software reset, is also immediate and initializes all memory locations with the respective reset values.

8.5 Register Maps

The TMP006 and TMP006B contain data registers that hold configuration information, temperature measurement

results, and status information.

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 (Figure 14) are used in

conjunction with data from the Temperature register to calculate the object temperature. Figure 14 summarizes

the Sensor Voltage register. The equation for the resultant object temperature is discussed in the TMP006 User

Guide (SBOU107).

The temperature register of the TMP006 and TMP006B is configured as a 14-bit, read-only register (as shown in

or a software reset, the Temperature Register reads 0°C (0000h) until the first conversion is complete.

8.5.3 Configuration Register (address = 02h) [reset = 0111010000000000]

Figure 16 describes the configuration register. This register determines the operational modes, conversion rate,

DRDY control, initiates a single conversion, performs a software reset, or puts the device into shutdown mode.

This register is read/write, and the pointer address is 02h.
