Analog Devices AD7284's design also includes two on-chip 2.5V voltage references. One voltage reference works with the primary measurement path, and the other is designated for the secondary measurement path. The integrated secondary measurement path validates the data on the primary 14-bit ADC. Other diagnostic features include the detection of open inputs, communication, and power-supply related faults.
The AD7284 offers a ±3mV maximum cell voltage accuracy, ±16mV typical battery stack voltage (TUE) accuracy, and very low measurement latency across 96 cells. The AD7284 Battery Monitoring System is ideal for li-ion battery monitoring, electric and hybrid electric vehicles, and stationary power applications.
