Operational sequence
This evaluation board comes with the AS1324 soldered on. The output voltage is set to 1.8V. For more
information which other output voltages are available please see the ordering information in the datasheet.
1.
If not present get the datasheet for the AS1324 from www.austriamicrosystems.com. Drive the IC on the
Evaluation board only with the recommended settings and values as described in the datasheet.
2.
Connect a +2.7V to +5.5V power supply (Vin “A” and GND “B”).
3.
Perform measurements at the measurement points.
If there are questions do not hesitate to contact us. See contact information at the end of the application note.
