Output Data Formats for Renesas Rad Hard Precision SAR ADCs

PublishTime：2023-03-28

●This application note discusses the output data formats available on the ISL73141SEH and ISL73148SEH rad hard precision SAR ADC products and details the configuration through the evaluation software iRADAnalyzer on their respective evaluation boards. There are a variety of formats that can be used to encode the digital output data from an ADC; therefore, it is important to understand how this is applied to the ISL73141SEH and ISL73148SEH. The purpose of this application note is to provide information on the available output data formats, explain their relationships, detail the configurations, and define the impact on the operation of these ADC products.
●Throughout this application note, the data formats are presented primarily as 14 bits. Figures and tables are provided to aid the reader in understanding these different data formats and how the device mode of operation impacts these data formats for these ADC products. In all cases, the analog input voltage (AIN ) is limited to a maximum value equal to the input reference voltage (VREF ) because the V REF voltage defines the full-scale input range of the ADC.
