2 *
3 *@verbatim
4 *The LTC6810 is multi-cell battery stack monitor that measures up to 6 series
5 *connected battery cells with a total measurement error of less than 1.8mV.
6 *The cell measurement range of 0V to 5V makes the LTC6810 suitable for most
7 *battery chemistries. All 6 cell voltages can be captured in 290uS, and lower
8 *data acquisition rates can be selected for high noise reduction.
9 *Using the LTC6810-1, multiple devices are connected in a daisy-chain with one
10 *host processor connection for all devices, permitting simultaneous cell monitoring
11 *of long, high voltage battery strings.
