7.5.2 Conversion Rate

The conversion rate bits, CR1 and CR0 located in the Configuration Register, configure the TMP103 for conversion rates of 8 Hz, 4 Hz, 1 Hz, or 0.25 Hz (default). The TMP103 has a typical conversion time of 26 ms. To achieve different conversion rates, the TMP103 performs a single conversion and then powers down and waits for the appropriate delay set by CR1 and CR0. Table 1 lists the settings for CR1 and CR0.

Table 1. Conversion Rate Settings

CR1 CR0 CONVERSION RATE
0 0 0.25 Hz (default)
0 1 1 Hz
1 0 4 Hz
1 1 8 Hz

After power up or general-call reset, the TMP103 immediately starts a conversion, as shown in Figure 13. The first result is available after 26 ms (typical). The active quiescent current during conversion is 40 μA (typical at 27°C, V+ = 1.8 V). The quiescent current during delay is 1 μA (typical at 27°C, V+ = 1.8 V).
