  • evaluation board AD7294-2SDZ


    Can you explain the meaning of "position B selects ..." in Table 3?

    There are pins and connectors on the evaluation board. How should I connect them in order to use this board with Arduino?

    Thank you in advance,

    Why does the AD7294 have a seperate internal DAC and ADC reference?

  • AD7294 DAC output spike at startup


    I have observed that the output DAC pins have as much as a 0.1V spike on powering the 7294 chip. This is a problem as they are controling a high voltage supply and I can't have that spiking from 0 when I power the chip on. Any advice, or is there…

    Can you store the minimum and maximum conversion results in autocycle mode?

  • RE: AD7294: What happens if the I2C bus is idle for a long period of time?

    When the AD7294 is in command mode it expects the conversion result to be read back from the Result Register within 5ms. If the I2C bus is "frozen" for longer than this then the AD7294 will abort the command mode operation and revert to an idle state…

  • LTC6804-2 and LTC6811-2 reference voltage 1 and 2 at 0V.


    I installed 2x LTC6811-2 and then 1x LTC6804-2 on the same board and I don't have any voltage reference output at anytime. The functional diagram in the datasheets shows that VREF1 should be always present as it's generated from V+. VREF2 is not…
