Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LTC6812-1 is a multi-cell battery pack monitor that can measure the voltage of up to 15 cells connected in series with a total measurement error of less than 2.2mV. The LTC6812-1 has a battery measurement range of 0V to 5V, making it suitable for most battery chemistries. All 15 cells can be measured in 245µs and a lower data acquisition rate can be selected for high noise rejection.
