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

section.

Memory Map

3 IAVDD and IDRVDD are measured with a −1 dBFS, 10.3 MHz sine input at a rated sample rate.

4 Single data rate mode; this is the default mode of the AD9484.
