the data from the input latches to the respective DAC latches
and updates both analog outputs. Alternatively, the LDAC in-
Plastic DIP (N-24)
put can be asynchronous or can be common to a number of
AD7237As for simultaneous updating of a number of voltage
channels.
AD7237A—68008 Interface
An interface between the AD7237A and the 68008 is shown in
Figure 14. In the diagram shown, the LDAC is derived from an
asynchronous LDAC signal, but this can be derived from the
address decoder as in the previous interface diagram.

AD7237A—6502/6809 Interface
Figure 15 shows an interface between the AD7237A and the
6502 or 6809 microprocessor. The procedure for writing data to
SOIC (R-24)
the AD7237A is as outlined for the 8085A/8088 interface. For
the 6502 microprocessor, the 2 clock is used to generate the
WR, while for the 6809 the E signal is used.
