What power supplies does the ADAS3022 require, and is there a power-on sequence
that should be adhered to?

 

The ADAS3022 requires these five supplies: AVDD = +5V, DVDD = + 5V, VDDH = +
15V, VSSH = - 15V, and VIO = 1.8V to 5V. There is NO power supply sequencing
required for the ADAS3022.

In order to operate the ADAS3022 from a + 5V single supply, the user would need
to generate the required +/-15V high voltage supplies using one of our
switching converters such as the ADP1613/14 in SEPIC-Cuk topology. Refer to
CN-201 for complete information on this test setup.
