Dear Product line engineer:
one thing need your supporting as below.
I use Pspice-for-TI to do simulation for supporting customer and need use DAC7811. then I'm a little puzzle for pin 1(DIG_ANA_IN) of DAC7811 symbol. how to use this pin? Could I directly add a 5V voltage or other voltage?
my understanding is that the voltage in Pin 1 of DAC7811 will be inversered for previously schematic, am I right? seems this pin means analog input voltage for relatived digital input code, right?
thanks for your supporting.
regards,
Bill
hi, Jones
nice to meet you here and thanks for your explain.
then I set the input voltage to 2V and expect output equal to ~ -2V. but the simulation result is -5V. is there any mistakes from pspice-model of DAC7811? my schematic and simulation result as below. could you please suggest? thanks.
regards,
Bill
Hi Bill,
I downloaded the model directly from TI's website and there were some helpful notes:
It looks like the input range is 0 - 1V, not 0 - VREF like I originally thought. I had never used this model before, so sorry for the confusion!
Best,
Katlynne Jones
