DAC8742H: MOD_OUT amplitude setting

Jerry Chen

Part Number: DAC8742H

Hi there,

Is TX_AMP to set the output voltage of MOD_OUT in HART MODE? If yes, should I change the load resistance to change amplitude from 400mVpp to 800mVpp?

Thanks.

Hi Jerry,

Setting TX_AMP to 'b10000 will give you an 800mVpp output. The load does not need to change for the higher amplitude.

Thanks,

Paul
