DIGITAL FEEDTHROUGH
The digital inputs to the AD7538 are directly connected to the
microprocessor bus in the preceding interface configurations.
These inputs are constantly changing even when the device is
not selected. The high frequency logic activity on the bus can
feed through the DAC package capacitance to show up as noise
on the analog output. To minimize this digital feedthrough
isolate the DAC from the noise source. Figure 13 shows an
interface circuit, which uses this technique. All data inputs are
latched from the bus by the CS signal. One may also use other
means, such as peripheral interface devices, to reduce the digital
feedthrough.
