Part Number: DAC38RF80
Other Parts Discussed in Thread: DAC38RF83

Hi TI,

We are using DAC38RF80 in our design.

We got confused with the description of GPI0,GPI1,GPO0 and GPIO1 pins.

Pin name and number is different in Pin Diagram and pin description table for DAC38RF80.

Pin Diagram of DAC38RF80 and DAC38RF83 is same for GPI/GPO signals but the description of GPI/GPO signals in pin description table of DAC38RF80 and DAC38RF83 is different.

Please tell us which pin name and number we should use for CMOS SYNC0&1, and which pin name and number should be grounded for GPI/GPO of DAC38RF80.

Thanks,

Lalit

Lalit,

Pin L7 is CMOS SYNC 0. Pin K7 is CMOS SYNC 1. GND pins L6 and M7.

Hi Jim,

So that means GPI/GPO pins have different configuration for DAC38RF80 and DAC38RF83?

Because in DAC38RF83 Pin L7 is CMOS SYNC0 and Pin L6 is CMOS SYNC1.

Is that true Jim?

Thanks,

Lalit

Lalit,

No. The pinout is the same for every part in the family. What you are seeing is an error somewhere in the data sheet. In the 83 data sheet, in the pin function table on page 11, it has the correct description.

Regards,

Jim
