Hi,
I'm in the process for selecting a proper DAC for our application. I'd like to optimize for lowest possible noise between 0.1 -- 150 Hz. DAC82002 is one candidate…

Hi there,
I'm looking for a DAC like the one attached (DAC8830) but with a maximum operating temperature of +200ºC. I haven't found any and don't know if there are in development.
Thanks in advance…

Hi TI,
I am considering using the DAC without an output buffer. From page 17 of the datasheet: "These DACs are capable of driving unbuffered loads of 60 kΩ". I assume all electrical characteristics are met for…
"I need help with the grounding connection of the DAC8830, as when connecting it to a microcontroller, I experience voltage drops in VREF and CS. Additionally, Vout shows no variation. I…
Hello Team,
The datasheet described the digital feedthough is 0.5nV-s. however my customer request waveform similar as following.
(This waveform from DAC8830 datasheet)
Is the data of digital…
The datasheet states in the section titled Power-On Reset on page 16 that "After power-up, the output from pin VOUT of the DAC8830 is 0 V."
In our hardware we have found this statement to not always hold true. After bootup…
Hello guys,
One of my customers is considering using DAC8830-EP instead of DAC8830ICDR due to very long lead time.
At this moment, they have the following questions. Could you please give…
I'm making a single supply design, and I'm concerned I won't be able to get a precise 5V reference off a 5V supply. I know current-feedback DACs can do this but wasn't sure about regular R-2R DACs, can I feed 2.5V into…
Hi team,
Could you share the ESD ratings information of DAC8830? I didn't find it in datasheet.

I see that the digital inputs are defined +-0.3V VDD, presumably there is a diode clamp protecting the inputs. I cannot find the current rating of the diodes protecting the input, is there a way to obtain this information?
Hello.
P/N:DAC8830IBDR
I am creating a delivery specification for this part number.
In the Qualification Summary, the results of ESD-HBM and CDM are described as "See data sheet".
However, the datasheet does not show the results…
Hi team,
My customer is considering to use DAC8830 with VDD shorted VREF. I found the linearity error depends on supply voltage and reference voltage, what else? (e.g. affect PSRR, etc.?)
Additionally, I'm curious about the linearity…
I need a voltage source that can be adjusted to the nearest millivolt with good temperature stability to replace a trimpot which is simply not precise enough, even a quality 21 turn one.
I have a 2.8v reference…
I want 4-20mA current loop with DAC for interfacing HART modem
Hi Team,
Customer is asking for DAC8830 FIT, can any expert please help?
It cannot be found in here.
