I believe I've configured my device correctly however I must have made a mistake since the output voltage out of my DAC's is only 0-1.25V instead of 0-5V. I'm using a voltage to CODE conversion factor of 3276.6 (Vout = CODE / 16383 x 2.5 * 2) and I've initialized the device as follows:
- CONFIG REGS (0x:
- Fast SDO enabled (clocking on falling edge)
- CRC Disabled
- All DAC's enabled
- GAIN REGS:
- Reference Voltage divider disabled (Ref Voltage Divider of 1)
- BUFF-GAIN for all DAC's enabled (Gain of 2)
I've attached some screenshot of my logic analyzer capture (Note: After initialization I set my output to 5V for all DAC's, which equates to a CODE=0x3FFF)
