SBOS473J March 2009 – February 2024 TMP112
PRODUCTION DATA
The default mode of the TMP112 family 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 TMP112 family for conversion rates of 0.25 Hz, 1 Hz, 4 Hz, or 8 Hz. The default rate is 4 Hz. The TMP112 family has a typical conversion time of 26 ms for SOT563-6 package and 10 ms for X2SON-5 package. To achieve different conversion rates, the TMP112 family makes a conversion and then powers down and waits for the appropriate delay set by CR1 and CR0. Table 7-5 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 a power-up or general-call reset, the TMP112 family immediately begins a conversion as shown in Figure 7-7. The first result is available after 26 or 10 ms (typical). The active quiescent current during conversion is 40 μA (typical at 27°C) for SOT563-6 package and 55 μA (typical at 27°C) for X2SON-5 package. The quiescent current during delay is 2.2 μA (typical at 27°C) for SOT563-6 package and 2.6 μA (typical at 27°C) for X2SON-5 package.
