DAC7718: oscillations on the reference input
Part Number: DAC7718
we observe the DAC7718 heating up to 45 degrees C when the negative -5V voltage is applied to AVss (through a 1kOhm resistor). The AVss is taking 2.5mA, its voltage is -2.5V.
When Avss is grounded, the device is not heating up. The AVdd is +15V so within the EC recommendation.
We need to apply negative voltage since it helped achieving reasonable accuracy of the output voltage.
Is it fine or should it be heating up like this?
Thanks for your help.
