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.
