Part Number: DAC8734 Team,
I'm posting this on behalf of my customer.
If using the DAC8734 with a 2.5V logic level, meaning IOVdd = 2.5V, what does the operation of the DAC look like? Specifically, page 5 of the datasheet shows a table with electrical…

Hello,
I am struggling with the following problem. I want to read back the default values of the command register, but it seems, that the respond of the DAC is incorrect.
The uC is sending: 0x80XXXX for the read operation of the…

Hi forum. For the prototype of my project I am using the DAC8734-EVM board due to electronic part shortage. Apart from that, the board is awesome since it is useful for hands-on approach. I have rewritten some lines of code to steer…
Hi Sanath,
The power off glitch is not very surprising. As I mentioned above, the device being off does not imply a hard short to GND, rather it is likely a higher impedance. What is surprising is that DAC channel 3 is doing something different than the…
Part Number: DAC8734 Hi Team,
My customer was under the impression that they could use the gain register to control the FSR of the Output independent of the outside connection path. I am not sure I understand the datasheet.
Is it capable of true Bipolar…

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: DAC8734EVM Other Parts Discussed in Thread: DAC8734 , DAC7734 Hi,
I just bought a new DAC8734 EVM board.
I try to powerup the DAC8734 considering the powerup sequence given in datasheet.
At first I connect the DVDD (+5V) and IOVDD (+3.3V) power…
Part Number: DAC8734 I have an DAC8734 set for a gain of 2 with output +/-15V. I have it set to 0V out (midscale). The DAC output is connected to a low-noise preamplifier that has a 100KHz low pass filter. When I measure the output of this preamp, I get…
