7.4.2 One-Shot Mode (M1 = 0, M0 = 1)

The TMP108 features a one-shot temperature measurement mode. When the device is in shutdown mode, writing a ‘01’ to the M1 and M0 bits starts a single temperature conversion. During the conversion, the M1 and M0 bits reads 01. The device returns to the shutdown state at the completion of the single conversion. After the conversion, the M1 and M0 bits read 00. This feature is useful for reducing the power consumption of the TMP108 when continuous temperature monitoring is not required.

As a result of the short conversion time, the TMP108 can achieve a higher conversion rate. A single conversion typically takes 27 ms and a read can take place in less than 20 μs. However, when using one-shot mode, 30 or more conversions per second are possible.
