AD684
DATA ACQUISITION APPLICATIONS
Figure 9 shows a typical data acquisition circuit using the
AD684 and the high speed 12-bit A-to-D converter, the
AD7672. Four input signals are simultaneously sampled by the
AD684 as the HOLD command is given. One of the four held
outputs is selected by the ADG201, quad CMOS switch, and
buffered by the AD711. The AD588 provides the reference
voltage with switches A-B and C-D selecting a –5 V to +5 V or
0 to +5 V input range.
