Part Number: DAC8734 Hi,
DAC8734 output is controlled by 1sec under stand-alone and LDAC actvie high.
After about 10min, setting fail or 0V output is occured.
Is there any advise for this issue?
I'm checking SPI timing.
Thanks.
Part Number: DAC8734 Hi sir,
Could you help me on this inquiry?
Some pins like AIN and VMON how to terminate if we are not going to use them ?
floating or connect to GND?
Thank u.

Part Number: DAC8734 We have 4 DAC8734's on the board. It has always worked, but after I reworked the board (that does not directly affect these DACs), all 4 DACs developed large output offsets. DAC0 has 100 to 200 mV of offset, DAC1 ~500mV, DAC2 ~300mV…
Part Number: DAC8734 once I dereset the DAC8734, the value of the reg0 should be 0x003C, but the chip returns 0x0000, I'm sure the chip is dereset and Load pin is tied to GND.
I have 45 DAC8734 chips on my PCB borad, and only a part of them are read…

Hi,
We have a load that needs a variable low noise programmable voltage between ±5V with around 250mA (we are using an op-amp buffer to support the current draw) .
We are…
Part Number: DAC8734 Hi,
We are using the DAC8734 DAC in our design. We have designed the Ref as 2.5V and for bipolar operation from +5V to -5V.
When we set the output to the maximum extreme (7f ff or 80 00) the values observed are only +4.74 &…
Part Number: DAC8734 Other Parts Discussed in Thread: ADS1278 , , DAC81408 Hi,
I want to use AVDD/AVSS = +/- 15 V, AGND = SGND = GND = 0V
REFGND = 0.25 V, REF = 5.25 V gain of 4 config.
This is within the maximum ratings, as REFGND may by different…
