1 See the AN-835 Application Note, Understanding High Speed ADC Testing and Evaluation, for a complete set of definitions and how these tests were completed.
2 The input range is programmable through the SPI, and the range specified reflects the nominal values of each setting. See the Memory Map section.
3 IAVDD and IDRVDD are measured with a −1 dBFS, 30.3 MHz sine input at rated sample rate.
4 Single data rate mode; this is the default mode of the AD9434.
5 Double data rate mode; user-programmable feature. See the Memory Map section.
