Dear TI team I want to know the connection requirements for LDAC , TRIGG and STATS if I am using microcontroller

Hello,

Depends on if you want to use the features associated with these pins or not.

LDAC is used to update all DAC outputs at the same time. Tie it low to use asynchronous mode and update each DAC after each write command. Connect it to your MCU and pull the pin high while writing to each DAC and pull it low to update all outputs at the same time.

TRIGG pin is used if you want to use toggle mode. TRIGG is edge triggered, so you can fix high or low if toggle mode is not used unused.

STATS in an output pin used in toggle mode.

Hello karlynne , If we dont want to use LDAC,STATS and TRIGG pins in our design so can you please let me know by default condition. But as I have seen for this DAC is it compulsory that it should be in asynchronous or synchronous mode. And if I am not using TRIGG than i am not able to take output of all 96 chains ? STATS should i need to give pull - up and pull-down configuration both option to detect reg A or Reg B

Hi Ankita,

LDAC can be pulled directly to ground which will select asynchronous mode. TRIG can be tied directly to ground. STATS is an output so you can leave it only.

You write to the DAC outputs via a register like any other DAC. The toggle mode is a separate mode that allows you to use an external clock pulse to quickly toggle between two preconfigured DAC outputs.

So I want to configure with this connection also we can use 96 channel DAC output properly na

Hi Ankita,

Yes, you can write to all 96 channels of the DAC with the above configuration. The features you were asking about were just optional.

can you tell me if i dont want to use few DAC output what is the default condition for unused pins

Hi Ankita,

You can leave any unused output pin floating (unconnected).

Can you please help me for REF1 and REF2 connection with refout generating REF501251DGK without jumper

0 Katlynne Jones over 1 year ago in reply to Ankita Rupam

HI Ankita

Not sure what you mean here. REF501251DGK is an onboard reference on the EVM. Are you trying to use the onboard reference or an external reference? Either way you need to place the jumper otherwise REF1 or REF2 will be left floating which is an invalid input.

Best,

Katlynne Jones
