AUTOMOTIVE PRODUCTS
The AD7927W models are available with controlled manufacturing to support the quality and reliability requirements of automotive
applications. Note that these automotive models may have specifications that differ from the commercial models; therefore, designers
should review the Specifications section of this data sheet carefully. Only the automotive grade products shown are available for use in
automotive applications. Contact your local Analog Devices account representative for specific product ordering information and to
obtain the specific Automotive Reliability reports for these models.
Z = RoHS Compliant Part.
W = Qualified for Automotive Applications.
The EVAL-AD7927CBZ can be used as a standalone evaluation board or in conjunction with the Evaluation Controller Board for evaluation/demonstration purposes.
The EVAL-CONTROL BRD2 board is a complete unit allowing a PC to control and communicate with all Analog Devices evaluation boards ending in the CB designators.
To order a complete evaluation kit, please order the particular ADC evaluation board, for example, EVAL-AD7927CB, the EVAL-CONTROL BRD2, and a 12 V ac
transformer. See the relevant evaluation board application note or data sheet for more information.
Linearity error refers to integral linearity error.
