-The [[http://www.analog.com/ad7280A|AD7280A]]contains an internal ±3 ppm reference that allows a cell voltage measurement accuracy of ±1.6 mV. The ADC resolution is 12 bits and allows conversion of up to 48 cells within 7 μs. It also has cell balancing interface outputs designed to control external FET transistors to allow discharging of individual cells and forcing all the cells in the stack to have identical voltages.+The [[adi>ad7280A|AD7280A]]contains an internal ±3 ppm reference that allows a cell voltage measurement accuracy of ±1.6 mV.

-The [[http://www.analog.com/AD8280|AD8280]] functions independently of the primary monitor and provides alarm functions indicating out of tolerance conditions. It contains its own reference and LDO, both of which are powered completely from the battery cell stack. The reference, in conjunction with external resistor dividers, is used to establish trip points for the over/undervoltages. Each cell channel contains programmable deglitching (D/G) circuitry to avoid alarming from transient input levels.+The [[adi>AD8280|AD8280]] functions independently of the primary monitor and provides alarm functions indicating out of tolerance conditions.
