1.2mV Accurate, Noise Immune Battery Stack Monitor Maximize Battery Pack Safety, Life, Capacity & Driving Range ® Safely extract the potential of large battery packs via precise monitoring of every cell. The LTC 6804 Battery Monitor measures cell voltage with less than 0.04% error, guaranteed. Measurement stability over time, temperature and operating conditions is achieved with a buried Zener voltage reference, similar to those in precision instrumentation. A programmable 3rd order noise filter keeps TM noise from corrupting cell measurements, and a 2-wire isoSPI interface provides a cost-effective, noise immune, 100 meter interconnection for multiple LTC6804s.
