Operation
After applying VDD, the device will initially be in the power down state. To operate the device, issue an SMBus
Send Byte protocol with the device address and the appropriate command byte to read ADC channel 0 or ADC
channel 1 (see Table 1). To obtain the conversion result, issue an SMBus Receive Byte protocol with the device
address. The data byte received will correspond to the value in the ADC register (0 or 1) specified by the previous
command. If a conversion has not been completed since power up (either through V
DD
or power up command),
the valid bit will be 0, and the data will not be valid. If there is a valid conversion result available, the valid bit
will be set (1), and the remaining 7 bits will represent valid data from the previously selected ADC register. Data
may be read repeatedly from the currently selected ADC register, and although it will remain valid, the ADC
register will not be updated until a new conversion completes for that channel (800 ms total since there are two
serial 400 ms per channel conversion times in standard mode). Note also that the command register itself may
be read, as a check to be sure that the device is communicating properly.
To power down the device for reduced power consumption, issue an SMBus Send Byte protocol with the device
address followed by 0 as indicated in Table 1.
