Part Number: DAC7821 Other Parts Discussed in Thread: OPA2992 Hello,
I have in my design a DAC7821 followed by the OPA2992 using the bipolar output circuit shown in Figure 29 of the DAC7821 datasheet. Due to limitations in our hardware, we are essentially…
Part Number: DAC7821 Other Parts Discussed in Thread: DAC82002 I need to generate a triangular waveform using the DAC7821 Chip, Is it possible to implement the same without the use of any negative supply/ the opamp used at output of the DAC chip has need…
Alex,
Unfortunately I am not really sure of the origins of LabKit Pro or ASLK Pro. I think these were largely developed outside of TI though they are using TI components and referenced on the TI University page. Therefore, I'm not really sure what the…
Part Number: DAC7821 Other Parts Discussed in Thread: OPA725 , OPA277 Hi Team, One of customer designed DAC7821 and OPA725 refer typical application in datasheet. They found abnormal singal waveform during the power on even if no input to DAC7821. They…
Part Number: DAC7821 Hello everybody. I am using DAC7821 which is a 12 bit parallel DAC which is interfaced to Infineon XMC4800 microcontroller. I am using it as unipolar output of the range 0V to 10V. If I write the DAC code to DAC data register output…
Part Number: DAC7821 Hello,
Our customer input 6Vpp 60~150kHz Sin wave, When they input high code to the DAC, there is no problem. However, if they input the value of 50 or less in decimal, the output was not decreased any further. Could you please…
Other Parts Discussed in Thread: DAC7821 , DAC8811 Hello:
In the FIG.25 of DAC7821's DATASHEET ,I think it should be only 2R at the last group （R and 2R series）.
Other Parts Discussed in Thread: DAC7821 Hi All,
Query 1)
We want to use DAC7821 in my design.Due to some other components in the board we want to give power to DAC7821 like this:
1st VDD(3.3V), and then after few seconds Vref.Until Vref generated…
Other Parts Discussed in Thread: DAC7821 Dear TI staff,
I want to know how to output the maximum frequency and minimum of the DAC7821.
It only comprises input latch, DAC register and 12-bits R-2R without external clock.
I can’t understand the operation…
