/*! LTC6811: Multicell Battery Monitors
*
*@verbatim
*The LTC6811 is multi-cell battery stack monitor that measures up to 12 series 
*connected battery cells with a total measurement error of less than 1.2mV. 
*The cell measurement range of 0V to 5V makes the LTC6811 suitable for most 
*battery chemistries. All 12 cell voltages can be captured in 290uS, and lower 
*data acquisition rates can be selected for high noise reduction.
*Using the LTC6811-1, multiple devices are connected in a daisy-chain with one 
*host processor connection for all devices.
