Hi Team,
We are using AMC7836EVM and SDM-USB-DIG. When we set 0xFFF(5V) for DACA0 from the TI GUI application, we are getting 5.44V at the DACA0 pin.
At that time IOVDD is 3.68V and VDUT is 3.68V.
What could be the reason for more voltage than expected?. Below is the table.
| DAC O/P Voltage Measurement | |||
| DAC Initial Hexa Value | Expected Voltage With the value of Hexa value | Measured Voltage | Difference |
| FFF | 4.99 | 5.44 | 0.44 |
| AFF | 3.43 | 3.76 | 0.32 |
| 8FF | 2.81 | 3.12 | 0.30 |
| 4FF | 1.56 | 1.76 | 0.19 |
Regards,
Harish
