Part Number: DAC9881 Hello all,
I am attempting to generate an analog 5-V sine voltage ([-2.5V;+2.5V]) using the DAC9881, but our home-made board yields the signal as in the figure below :
(this is an Excel curve based on data captured on an oscilloscope…
Part Number: DAC9881 Hi Texas
We have configured DAC for 1.111 volt however, we are getting massive oscillations at output (attached). We chose this DAC as we were expecting higher eNOB >14 bit however we are yet to achieve this. Our ref_L is 0.943V…

Hi,
i am using the DAC9881 to generate 0V-10V DC signals.
Attached you can find my schematics.
When sending 0x0570a to the device and activating LDAC (Negative pulse with 10us length), the output changes from 0V to approx…
Part Number: DAC9881 Hi team,
My customer is evaluating DAC9881 in their project.
And they test the Zero-scale error is 13mV, which is larger than the 32LSB on the datasheet.(The REF is 5V).
Could you please help give some comments about the problem…
Part Number: DAC9881 Dear sir
i study DAC9881EVM USER GUIDE,I find dac9881 operating system is WINDOWS XP
does it support other operating system like windows10. etc
thanks!!
TIA
Part Number: DAC9881 Hello,
I'm confusing about SLAU279A 's figure 8.
Since DAC9881 is designed as bufferd output mode, so internal buffer may lead offset voltage and headroom voltage.
They may crash the linearity of DAC. My problem is:
Q: When…
Part Number: DAC91001 Other Parts Discussed in Thread: DAC9881 , Hi team,
DAC9881can not linearly output 0-10mV, is it because the output type is Buffered Voltage?

Part Number: DAC9881 Hi team,
My customer found sometimes output voltage is not correct after power-on. I have checked the power up sequence and RSTSEL &USB/BTC setting. No suspect was found. I would like to know if anything else I could take a look…
