I'm asked AD5666-EP POR function from our customer.
The customer needs DAC which can output midscale after powered on.
And he needs -55 to 125°C temperature range too.
In the datasheet of AD5666 , power-on reset function is described in…
I am trying to use an external DAC connected to the ADuC845. While I could use the SPI on the microcontroller to write information and update the DAC, I am already using Timer2 as an external input counter. I have written my own transfer function to the…
I use the AD5666 quad 16bit DAC in my application.
During my calibration routine (to calculate gain and offset error from the circuit) I see curios output voltage.
You see a extract from the calibration solution graph.
X-axis is the set value in…

By connecting the POR pin low, the AD5666 output powers up to 0 V; by connecting the POR pin high, the AD5666 output powers up to midscale.
