7.4.1.3 Continuous Conversion Mode (CC)

When the MOD[1:0] bits are set to 00, the TMP116 operates in continuous conversion mode. In this mode, the

device continuously performs temperature conversions as illustrated in Figure 19 and updates the temperature

result register at the end of every conversion or averaging cycle. As described in the Conversion Cycle section,

every conversion cycle consists of an active conversion period followed by a standby period whose duration can

be configured using the CONV and AVG bits in the configuration register. The configuration is based on the

temperature accuracy, power consumption, and temperature update rate. At the end of a conversion, the

Data_Ready flag in the configuration register is set. The Data_Ready flag is cleared by reading the configuration

register or the temperature result register. The state of the Data_Ready flag can also be monitored on the

ALERT pin by setting the DR/nAlert_EN bit in the configuration register.

7.4.1.4 Shutdown Mode (SD)

When 01 is written to the MOD bits in the configuration register, the device instantly aborts the currently running

conversion and enters a low-power shutdown mode. In this mode, the device powers down all active circuitry. In

SD mode, the device typically consumes only 250 nA, which makes the TMP116 suitable for low-power

consumption applications, such as battery-operated systems.
