ZHCSIX4I August 2007 – June 2024 TMP102
PRODUCTION DATA
The default mode of the TMP102 device is continuous conversion mode. During continuous-conversion mode, the ADC performs continuous temperature conversions and stores each results to the temperature register, overwriting the result from the previous conversion. The conversion rate bits, CR1 and CR0, configure the TMP102 device for conversion rates of 0.25 Hz, 1 Hz, 4 Hz, or 8 Hz. The default rate is 4 Hz. The TMP102 device has a typical conversion time of 10 ms. To achieve different conversion rates, the TMP102 device makes a conversion and then powers down to wait for the appropriate delay set by CR1 and CR0. Table 6-5 lists the settings for CR1 and CR0.
CR1 | CR0 | CONVERSION RATE |
---|---|---|
0 | 0 | 0.25 Hz |
0 | 1 | 1 Hz |
1 | 0 | 4 Hz (default) |
1 | 1 | 8 Hz |
After power-up or general-call reset, the TMP102 immediately starts a conversion, as shown in Figure 6-5. The first result is available after 10 ms (typical). The active quiescent current during conversion is 55 μA (typical at +27°C). The quiescent current during delay is 2.6 μA (typical at +27°C).
