7.5.4 One-Shot (M1 = 0, M0 = 1)

The TMP103 features a One-Shot Temperature Measurement mode. When the device is in Shutdown mode, writing a 01 to bits M1 and M0 starts a single temperature conversion. During the conversion, bits M1 and M0 read 01. The device returns to the shutdown state at the completion of the single conversion. After the conversion, bits M1 and M0 read 00. This feature is useful for reducing power consumption in the TMP103 when continuous temperature monitoring is not required.

As a result of the short conversion time, the TMP103 can achieve a higher conversion rate. A single conversion typically takes 26 ms and a read can take place in less than 20 μs. When using One-Shot mode, 30 or more conversions per second are possible.
