Power Supplies

What power supplies does the ADAS3023 require?

 

The ADAS3023 requires these five supplies: AVDD = +5V, DVDD = + 5V, VDDH = +
15V,
VSSH = - 15V, and VIO = 1.8V to 5V. The user must bring up the ADAS3023 power
supplies in the following sequence in order to operate it normally:
1. VIO
2. VDDH
3. VSSH
4. DVDD
5. AVDD
6. REFx

In order to operate the ADAS3023 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.
