EVALUATION KIT AVAILABLE MAX14920/MAX14921 High-Accuracy 12-/16-Cell Measurement AFEs General Description The MAX14920/MAX14921 battery measurement analog front-end devices accurately sample cell voltages and provide level shifting for primary/secondary battery packs up to 16 cells/+65V (max).
The MAX14920 monitors up to 12 cells, while the MAX14921 monitors up to 16 cells.
Both devices simultaneously sample all cell voltages, allowing accurate state-of-charge and source-resistance determination.
All cell voltages are level shifted to ground reference with unity gain, simplifying external ADC data conversion.
The devices have a low-noise, low-offset amplifier that buffers differential volta...
