73 / 95 page  Data Sheet AD4080 CONFIGURATION REGISTERS analog.com Rev. 0 | 73 of 95 The features of the AD4080 family have been designed to simplify the application of low latency data capture to a broad array of measurement applications. This simplification is achieved through customization of the data interface, data path, and data access method to satisfy both measurement and the host processor inter- face requirements via the available configuration registers. The register space was organized in contiguous regions by function to streamline device configuration as described in Table 30. As a result, the interface streaming functions (see Instruction Mode Selection) can be leveraged to simplify device configuration to a single SPI frame consisting of an instruction word and associated data. For most applications, modifications to the register space address range of Address 0x15 to Address 0x29 are sufficient. Modification of content in the configuration interface and product ID space (Address 0x00 to Address 0x11) is only necessary to initiate a software reset or to change the configuration access method. Note that changes to the configuration access method are outside the scope of this document. For assistance with these options, contact your local Analog Devices sales representative or submit a request for technical assistance through the Precision ADCs page on the ADI Engineer Zone at https://ez.analog.com/data_con- verters/precision_adcs/.
