Z80 with MX7534/MX7535
Figure 12a is an interface circuit for the Z80, using the
MX7535. This is an example of an 8-bit processor inter-
face for these DACs. Figure 12b shows the schematic
for the MX7534.
MC6809 with MX7534
Figure 13a shows an interface circuit that enables the
MX7534 to be programmed using the MC6809 8-bit
microprocessor. Use the 16-bit D accumulator to simplify
data transfer. The two key processor instructions are:
LDD
Load D accumulator from memory
STD
Store D accumulator to memory
MC6502 with MX7534
Figure 13b shows an interface diagram for the MC6502
using the MX7534.
________________Digital Feedthrough
In the interface diagrams shown in Figures 9–13, the
digital inputs of the DAC are directly connected to the
microprocessor bus. Even when the device is not
selected, activity on the bus can feed through on the
DAC output through package capacitance and appear
as noise. To minimize noise, isolate the DACs from the
digital bus, as shown in Figures 14a and 14b.
