Hi Ray,
You can take a look at this figure from TIPD137 :
With a positive reference in the four quadrant figure (the blue regions), codes 0x0000 to 0x7FFF represent the negative output voltage, and codes 0x8000 to 0xFFFF represent positive voltage.

Hello Iven,
The Engineer who primarily supports these products is located in India and will be observing the local Independence Day holiday tomorrow. I will temporarily help out here until his return.
Is it possible for us to look at schematic details…
Other Parts Discussed in Thread: TIPD137 , DAC8812 , DAC8811 Hello,
I would like to know if you have an example for the PCB layout of the DAC8812ICPW ?
Are there constraints on the routing of the components ?
Bests regards
Alpha,
I would suggest you refer your customer to TIPD137 , a design document we created to help guide people on the selection criteria of the amplifier used in the transimpedance stage of a multiplying DAC design.
A specific recommendation depends on…
Hi Mikael,
You are correct, when looking in from the OUT-pin, the impedance changes by code.
There is no easy way to determine the impedance at each code. If you want some more detailed information to calculate it take a look at TIPD137. The document…
Other Parts Discussed in Thread: DAC8812 , OPA2132 , TIPD137 Hi,
I'm planning to implement a volume control using a DAC8812. I'm just wondering which oamp should I use after the DAC8812? ...I think the proper term for this application is "unipolar…
Hi Paul,
1. Current tCSS timing is setting 0ns base on Figure 1. I will change tCSS timing from 0ns to 5ns, ok?
2. Regarding the schematic, we are based on DAC8811 as attached file. I cannot found any mistake...
Do you mean that VREFA and VREFB of DAC8812…
