Removing Ground Noise in Data Transmission Systems
Texas InstrumentsAlthough it is commonly stated that isolating interfaces removes ground potential differences (GPD) and ground loops it is also often unknown how and where these GPDs originate what their waveforms or frequency content is and why ground loops can represent a real nuisance.This application report explains how electrical installation systems wired correctly (or incorrectly) in combination w
Configuring the bq34z100 Data Flash
Texas InstrumentsThe bq34z100 has many data flash constants that can be used to configure the device with various options to customize the behavior and features of the gas gauge. The data flash of the bq34z100 is divided into sections, which are described in detail in this document.
