TEMPERATURE, BATTERY, AND SUPPLY VOLTAGE MEASUREMENTS
The ADE5166/ADE5169/ADE5566/ADE5569 include tem-
perature measurements as well as battery and supply voltage
measurements. These measurements enable many forms of
compensation. The temperature and supply voltage measurements
can be used to compensate external circuitry. The RTC can be
calibrated over temperature to ensure that it does not drift. Supply
voltage measurements allow the LCD contrast to be maintained
despite variations in voltage. Battery measurements allow for low
All ADC measurements are configured through the SFRs, as
shown in Table 49.
The temperature, battery, and supply voltage measurements can
be configured to continue functioning in PSM1 and PSM2 modes.
Keeping the temperature measurement active ensures that it is
not necessary to wait for the temperature measurement to settle
before using it for compensation.
