1.4.2 Interface to TI's DAC
All the TRF370x devices work well with TI's DACs. Figure 4 shows an example of the interface network
between a DAC56x2 and a TRF370315. Figure 5 shows an example of interfacing the DAC568x to the
TRF370333 with options for selecting the desired amount of attenuation between the two. Additional
interfacing networks for each modulator can be found in their respective data sheets or by using the DAC
interface calculator (
