TMS320F28P659DK-Q1: DAC output pull down resistor question

Huihuang Chen

Hi Champ,

As we know F28x7x device with 50Kohm pull down resistor on the DAC output pin which cannot be disabled, may i know F28P65x DAC output pin with pull down resistor or not?

Even from Migration guide Between TMS320F2837x and TMS320F28P65x , i still didn't found these info.

Hello Huihuang,

Thanks for bring this into my attention.

The pull-down resistor has been removed for TMS320F28P65x. We need to update the Migration Guide.

Regards,

Hadi

Hello Hadi,

Could we also add some note on SPRU566 file Table 3-28. Digital-to-Analog Converter (DAC) Module Type Description to show this difference ?
