THEORY OF OPERATION
The DAC7664 is a quad voltage output 16-bit DAC. The
architecture is an R2R ladder configuration with the three
most significant bits (MSBs) segmented, followed by an
operational amplifier that serves as a buffer. Each DAC
has its own R2R ladder network, segmented MSBs, and
output op amp, as shown in Figure 53. The minimum
voltage output (zero-scale) and maximum voltage output
(full-scale) are set by the internal voltage references and
the resistors associated with the output operational
amplifier.
The digital input is a 16-bit parallel word and the DAC input
registers offer readback capability. The converters can be
powered from either a single +5V supply or a dual
±
5V
supply. The device offers a reset function that immediately
sets all DAC output voltages and DAC registers to
mid-scale (code 8000h) or to zero-scale, code 0000h. See
Figure 54 and Figure 55 for the basic operation of the
DAC7664.
