Part Number: DAC7678 Tool/software: Hello.
I have a problem in my design (or i don't and just don't understand how it works).
1. I designed with the DAC7678SRGET and per the datasheet page 23 Vo should be Vo=(DIN/409)*2*Vrefout - my VREF is internal…
Part Number: DAC7678
Tool/software:
From the datasheet, the DAC supports 3 I2C standards:
1. Standard Mode (100kHz)
2. Fast Mode (400kHz)
3. High-speed mode (3.4MHz)
Accidentally, I had configured my MCU's I2C clock speed for 1MHz and released a product…

Tool/software:
I have a design that has 5 DAC7678SPW DACs on two separate I2C buses. In this application, I want to write to all but 5 of the 40 DAC channels then toggle the LDAC pin low then high to transfer the data to the DACs…
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 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 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 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…
