GR / SR GET / SET A2D CONFIG REGISTER (Continued)

Set the bits required for the application.

Notes:

High Range must be greater than or equal to the Normal Range. If SET MODE Bit1 (Autorange) is not set, High Range will be

ignored. If it is set, the sensor will automaitcally switch between the two ranges specified when necessary.

Reading intervals 13 ms and below utilize hardware averaging, 26 ms and above start using software averaging with a 13 ms

hardware interval time. If it is necessary to capture and report fast current spikes, use fast reading intervals otherwise they will be

averaged out.

Set the Vbus MAX voltage to the highest peak voltage expected. If using the sensor on the highside with voltage measuring, use

300 VDC range or lower.

Value is an unsigned Int16. A2D CONFIG default is: 0x035D

Example: Vbus Max Voltage 300 VDC, High Range 5X Nominal, Normal Range 1.25X Nominal, Reading Interval 820 ms (0x335D).
