Solved. Reason was outside of AD5676R part. Internal reference disable capability in AD5676R in TSSOP package works.
Is this true for the AD5676R as well that readback is not supported in daisy-chain mode?
What is the difference between AD5676 and AD5676R?
Question: Figure 46 on Rev B. of Datasheet of AD5672R/AD5676R. What is the test condition for this figure? One DAC change at a time and they are all compiled later? Is this just one DAC changed once or multiple times?
I answer by myself.
Both are correct value.
Page 6 mean Reset signal timing specification that necessary to recognize as a reset signal by AD5672R/AD5676R.
Page 27 mean minimum time to complete Reset operation (include internal analog circuit). This…
Do you really intend to create pulses going from 2V to a certain value, then back to 2V?
What is the application of this circuit?
You may consider using AD5676R which has 8 channels and can output 0 to 5V using a gain of 2.
However, the fastest update…
to add to what msamera said, you can get a better quality sinewave by adding more data points per period. This obviously requires writing more data to the DAC channels. The AD5628 and AD5668 are similar to the AD5629 and AD5669 but have an SPI interface…
Apologies for the delay. You may want to take a look at AD5676R, an 8-channel 16-Bit nanoDAC+ with 2 ppm/°C reference, and the AD5668(older part) which is an octal, 16-Bit voltage output denseDAC With 5 ppm/°C on-chip reference. Also, CN-0182 uses…
