SBOS891B October 2018 – April 2021 TMP144
The TMP144 features a One-Shot Temperature Measurement mode. When the device is in Shutdown mode, writing 01 to bits M[1:0] in the configuration register, starts a single temperature conversion. During the conversion, the bits M[1:0] read 01. The device returns to the shutdown state at the completion of the single conversion. After the conversion, bits M[1:0] read 00. This feature is useful for reducing power consumption in the TMP144 when continuous temperature monitoring is not required.
As a result of the short conversion time, the TMP144 can achieve a higher conversion rate. A single conversion typically takes 26 ms and an individual read can take place in less than 300 μs. When using One-Shot mode, 30 or more conversions per second are possible.
