THEORY OF OPERATION
The DAC7731 is a voltage output, 16-bit DAC with a +10V
built-in internal reference. The architecture is an R-2R ladder
configuration with the three MSB
’
s segmented, followed by
an operational amplifier that serves as a buffer, as shown in
Figure 1. The output buffer is designed to allow user-
configurable output adjustments giving the DAC7731 output
voltage ranges of 0V to +10V,
–
5V to +5V, or
–
10V to +10V.
Please refer to Figures 2, 3, and 4 for pin configuration
information.
The digital input is a serial word made up of the DAC code
(MSB first) and is loaded into the DAC register using the
LDAC input pin. The converter can be powered from
±
12V
to
±
15V dual analog supplies and a +5V logic supply. The
device offers a reset function, which immediately sets the
DAC output voltage and DAC register to min-scale (code
0000
H
) or mid-scale (code 8000
H
). The data I/O and reset
functions are discussed in more detail in the following sec-
tions.
