11 / 12 page AD7845 REV. B –11– Figure 23 and 24 are the interface circuits for the Z80 and MC6809 microprocessors. Again, these use the same basic format as the 8085A interface. Figure 23. AD7845 to Z80 Interface Figure 24. MC6809 Interface DIGITAL FEEDTHROUGH In the preceding interface configurations, most digital inputs to the AD7845 are directly connected to the microprocessor bus. Even when the device is not selected, these inputs will be con- stantly changing. 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 25 shows an interface circuit which uses this technique. All data inputs are latched from the busy by the CS signal. One may also use other means, such as peripheral interface devices, to reduce the digital feedthrough. Figure 25. AD7845 Interface Circuit Using Latches to Minimize Digital Feedthrough |
