Part Number: DAC91001 Does this model have a corresponding evaluation board? Our customer has made five prototypes and found that the output voltage accuracy is not enough. The data manual says that it is ± 1 LSB accuracy. The output voltage accuracy…
Part Number: DAC91001 Other Parts Discussed in Thread: OPA189 Hello,
I'm using a DAC91001 on my board for a 0-5V output span. Datasheet indicates that REFNF should be tied to a 0V when used in unipolar output.
The way it's done in the reference design…
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?

Hi Anna,
The DAC82001 would be a great fit here. It is an unbuffered device, so you will need to add a discrete output amplifier to achieve the ±10V. You could also consider the DAC91001 as well.
Thanks,
Paul
Part Number: DAC81001 Other Parts Discussed in Thread: DAC91001 , DAC11001B Hello,
I want to generate a sinusoidal signal with a high SINAD between frequencies 100Hz to 20kHz. For that reason I found DAC81001 ( DAC91001 and DAC1001 are also fine). When…
Hi Karthikeyan,
For the high accuracy DAC, I think you should look at the DAC11001 or DAC91001. For the high frequency DAC, you will probably need to look at TI's high-speed data converters. Most precision DACs have a max sample rate of 1Msps to 10Msps…
Dear Kai, Thanks for your reply.
I am design a digital controller for driving a Cambridge galvanometer 6220H - 6240H. The galvanometer specifications are,
Usually, 671XX or DC2000 servo is used to drive 6240H, Its specification are
Two DAC from TI.com…
Hi Vitor,
You cannot bypass the filter on the PCM1789. You can on some other devices in the PCM179x family, like the PCM1792A.
You could also look at some of our precision DACs, like an MDAC (DAC8811) or unbuffered R-2R DAC11001A (DAC81001, DAC91001)…
Hi,
You are correct, DAC11001A is more precise than DAC9881.
We have 18bit equivalent of DAC11001A which is DAC91001. May I know what kind of application you are planning to use with DAC11001A?
Regards,
AK
Hello Cynthia :
Thank you for your kindly reply! and base on your notes,
>> What is the source of the input?
For dynamic test : the source of ADC may come from Audio precision directly without capacitor on the input path.
For the static or linear…
