- Delta-Sigma ADC Design for Bridge Sensor ApplicationsPDF, 98 Kb, Archivo publicado: sept 30, 2011
This application report reviews several different types of bridge sensors, including characteristics of each type, and discusses the key parameters of delta-sigma (О”ОЈ) analog-to-digital converters (ADCs) at the system level. Additionally, the parameters of a О”ОЈ ADC are considered for use in common bridge sensor applications - Industrial data-acquisition interfaces with digital isolatorsPDF, 153 Kb, Archivo publicado: sept 16, 2011
