In addition, the ADC can be used to measure the internal VCC (shown as VBAT in Figure 9) voltage level or the chip temperature. The required voltage reference (VREF) to the ADC can be selected from multiple sources, including an on-chip 0.8V reference (V0P8), the VCC voltage divided by 2, or external channels. The VREF shall not exceed 0.8V. The input voltage range to the ADC shall be between 0V and 2*VREF. Figure 9 : Sensor ADC block diagram 4.4.1. On-chip VCC monitoring Measured at: Ta = 25°C, VCC=3.0V, unless otherwise noted (if On-chip VCC monitoring is used, VCC should not be greater than 3.0V). Table 6 : VCC monitoring characteristics Parameter Test conditions Min. Typ. Max. Unit Resolution Using on-chip V0P8 as reference 1.85 mV/LSB Range Input to ADC = 0.4*VCC. Input range of ADC is 0V - 1.6V (FS). 1 3.6 V Accuracy With VREF calibration only -3.3 1.1 3.3 % With ADC offset and VREF calibration -0.9 0.3 0.9 % |
