Typical Applications (Continued)
D DOUBLING THE SYSTEM CHANNEL CAPABILITY
This is done in two different ways First we can use second
level multiplexing with speed benefits as shown in
Figure 9
A fast 2-channel multiplexer made by the dual analog
switch AM182 accepts the outputs of each 8-channel MUX
LF13508 and then feeds them sequentially into an 8-bit
successive approximation AD converter With this tech-
nique the throughput rate of the system can again be made
independent of the LF13508 speed Looking at the timing
diagram when the AD converter converts the analog value
of an upper multiplexer channel we switch channels in the
lower multiplexer for the next conversion This can be done
provided that
TMUX s TC a 1CP
The LF356 connected as unity gain buffers are used be-
cause of the low input impedance of the AD they are con-
nected between multiplexers for speed optimization With a
maximum clock frequency of 45 MHz

An alternate way to increase the system channel is shown
in
Figure 10 where the enable pins are used to disable one
MUX while the other is sampling With this method many 8-
channel multiplexers can be connected but the parasitic
capacitance at the common output node will keep increas-
ing and will eventually degrade the settling time ts(ON)
Also the MUX speed will now affect the system throughput
If for instance this method was used instead of second
level multiplexing the system of
Figure 9 will lose half of its
speed If however speed is not the prime system require-
ment the approach of
Figure 10 is more cost effective
E DIFFERENTIAL INPUT SYSTEMS
Systems operating in industrial environments may require
an instrumentation amplifier to separate the desired analog
signal
from
any
common-mode
signal
present
The
LF11509 was designed to provide 4 pairs of differential in-
put signals to the input of an instrumentation amplifier for
