AFE7225: AUXDAC_A and AUXDAC_B output voltage is not matching with same register configured values

Hi TI Support team,

         We are configured both AUXDAC_A and AUXDAC_B channels with same external and internal termination resistor values and written same values for both 0x248 and 0x249 registers. But the measured voltage is not matching with both channels.

Please let me know why both channel outputs are not matching??

Hardware configuration:

For both AUXDAC_A and AUXDAC_B channels 402ohm external termination resistor is used.

Software configuration:

Below listed registers are configured to enable and control the AUX DAC output current.

Register 0x242 : A3 ( To enable both AUX DAC with internal 400ohm resistors)

Register 0x248 and 0x249 register are written with below values to set different output current and output voltage is measured.
