Hello Huck,
When performing the I2C read transaction, were you able to verify the DAC7573 ACKs? Your procedure above does look correct when comparing to the datasheet, but can you supply an oscilloscope capture for reference?
You've indicated…
Hi Tom,
I have the same Problem with DAC8574.
We use 5 of them on one I2C bus.
Readback from 3 of them works fine, but two sharing the same I2C address respond both to the readback command even they have different A2 addresses.
Could you please…
Part Number: DAC7574 Other Parts Discussed in Thread: DAC7573 Tool/software: On page 25 of the DAC 7574 datasheet, the following is stated regarding the Reference Voltage in relation to the Supply voltage: " The reference voltage applied to the DAC7574…
Hen,
Unfortunately such a device does not exist in our portfolio and personally I have not seen such a device available on in industry (though it still could exist, of course). I believe you would need to look into discrete options perhaps based on…
Hello Ted,
I assume that the Two-Wire, I2C-compatible interface of the DAC7678 is what gave the customer issues.
Based on the specs you mentioned I can recommend the DAC7573 and the DAC7574.
The main difference between the DAC7573 and the DAC7574…
Hi Borja,
Any progress in getting the LED to light up?
The R_SWT and IR_SWT signals look the same in both waveforms... so the switching should be okay.
Can you compare the DAC0_A and DAC0_B voltages when running with DSP vs running with FPGA…
TB,
DAC7554 may be your best bet in terms of simplicity and as a novice with the SPI interface. This is a simple 16-clocks wide frame that will interface your MSP430 pretty well and the pin out is just the essentials. Alternatives I would suggest are…
Hi Dave:
The AFE card i am using is manufactured by TI, which uses ADS8328 as ADC.
I think the problem is lying in setting DC Offset for second amplifier which is supplied from
channel C of DAC7573. But i don't know how to adjust its setting…
