DAC707/708/709

signal lines need to be isolated. The data is applied to pin 11
in a serial bit stream, MSB first. The WR input is used as a
data strobe, clocking in each data bit. A RESET signal is
provided for system startup and reset. These three signals
are each optically isolated. Once the 16 bits of serial data
have been strobed into the input register pair, the data is
strobed through to the D/A register by the “carry” signal out
of a 4-bit binary synchronous counter that has counted the
16 WR pulses used to clock in the data. The circuit diagram
is given in Figure 10.
CONNECTING MULTIPLE DAC707s
TO A 16-BIT MICROPROCESSOR BUS
Figure 11 illustrates the method of connecting multiple
DAC707s to a 16-bit microprocessor bus. The circuit shown
has two DAC707s and uses only one address line to select
either the input register or the D/A register. An external
address decoder selects the desired converter.
BURN-IN SCREENING
Burn-in screening is an option available for the DAC707.
Burn-in duration is 160 hours at the temperature shown
below (or equivalent combination of time and temperature).

APPLICATIONS
LOADING THE DAC709 SERIALLY
ACROSS AN ISOLATION BARRIER
A very useful application of the DAC709 is in achieving
low-cost isolation that preserves high accuracy. Using the
serial input feature of the input register pair, only three
