Part Number: DAC121C085 Other Parts Discussed in Thread: DAC63001 , DAC63204
Hi team,
is there any Alternative part like DAC121C085 but with Nonvolatile Memory, better also has 9 I2C address as well, thanks.
Part Number: DAC121C085 Hi,
I see that the full-scale error in the data sheet is -0.1 %FSR typical, and -0.7 %FSR maximum. This might be basic, but I'm confused by the negative sign. Does that mean the error will always be less than the "true value…
Part Number: DAC121C085 Hi,
Is there an advantage in noise performance of connecting VA and VREF to the same supply? Any ratiometric advantage of having those two supplies being the same and hence moving together? Or is the noise performance solely…
Part Number: DAC121C085 What is the default value for DAC register? I'm using it with external reference source of 2.5V.
I couldn't find it on the datasheet
Thanks,

Hi Paul,
Thanks for your support.
For DAC121C085 support for external reference voltage.
So we used Noise free 2.5V regulator output (LP2980) connect to the DAC VREF pin 7.
Need your help to understand the below points since i could not find application…
Part Number: DAC121C085 Other Parts Discussed in Thread: ENERGIA , DAC161S997 Hi,
I am trying to use DAC121C085 with msp432p401R and i need an example code. Is there an example code ? Thank you.
Hello,
R1 and R3 set the zero-scale current based on the reference (4mA). R4 and R5 set the span (16mA) based on the DAC output voltage. This is shown in Section 2.1 of the reference design guide. R5 in Figure 2 corresponds to (R1+R3) in the schematic…
Note: pointer gives the PD value (PD0 and PD1) which can only be 0-3.
Whereas writeByte gives the 12Bit DAC value (D0 -D 11) (0-4095) (changing the name would be good as this is not a byte).
I recommend to study the DAC datasheet, esp. (DAC Register…
