The last two example circuits could be used where mul-
tiple bridge circuits are involved and bridge output can be
multiplexed onto a single LTC2411, via an inexpensive
multiplexer such as the 74HC4052.
Figure 17 shows the use of an LTC2411 with a differential
multiplexer. This is an inexpensive multiplexer that will
contribute some error due to leakage if used directly with
the output from the bridge, or if resistors are inserted as
a protection mechanism from overvoltage. Although the
bridge output may be within the input range of the A/D and
multiplexer in normal operation, some thought should be
given to fault conditions that could result in full excitation
voltage at the inputs to the multiplexer or ADC. The use of
amplification prior to the multiplexer will largely eliminate
errors associated with channel leakage developing error
voltages in the source impedance.
