Part Number: DAC7678 In my application, I would like to update all 8 channels of the DAC as quick as possible. If I start updating with DAC channel A, can I continue to send the 2 bytes required for each of the other 7-DAC channels without starting a…
Part Number: DAC7678 Is it possible to send a global command to all 3 DAC7678 DACs on the same I2C bus that will cause them to re-examine the ADDR0 pin and establish a new address?
I'm about to test a new design that I use a floating ADDR0 pin to select…
Part Number: DAC7678 We are using DAC7678 and we have noticed that a very small number of devices with floating address pin initiate with a wrong address when being powered up with a slow ramp rate. Changing the ramp rate is not desirable.
Is there a…
Part Number: DAC7678 Hello,
The datasheet for the DAC7678 states " The internal reference in the DAC7678 is disabled by default for debugging, evaluation purposes, or when using an external reference." Does this mean that we should disable the internal…
Part Number: DAC7678 Other Parts Discussed in Thread: DAC60508 Hi all
My customer is evaluating the DAC7678 and they would like to power this DAC from a +3.3V.
What accuracy / resolution can they expect ?
Will they get lower accuracy / resolution compared…
Part Number: DAC7678
The DAC7678 datasheet both lists the maximum output current capability as +/-20mA ("Specified by design or characterization; not production tested.") and also later states that the maximum supported load for the output buffers is…
Part Number: DAC7678EVM Other Parts Discussed in Thread: TMS320F28377S , I'm interfacing with the DAC7678EVM using a TMS320F28377S as the I2C master controller. I am writing a sequence of bytes to power up the DAC Channel and write a value to it

Part Number: DAC7678 I am using eight DAC7678 in a system. The addresses are set for each one by jumpers on the card. All addresses for which the address pins are pulled high or low work properly. All addresses for which one pin is left open do not. They…
Part Number: DAC7678 Hello, I don't know if this question could be related to this one, but the datasheet is quite confusing on this matter. I am trying to read out the power down status of each channel, with the read command described on Table 18. …
