For a temperature range of 0
°
C to 1000
°
C, the delta voltage
change of the “E” type thermocouple is 58mV. The output
voltage of the multiplexer is filtered and buffered by a single
supply op amp, U
2
. The affect of changing the reference
voltage is summarized in Table III and Table IV.
Although a thermocouple was used to illustrate the function
of this circuit, other sensing devices can also be used making
the multiplexer more useful. With this simple circuit the
digital control can vary the gain coefficient from 1 to 50X.

TABLE III. By Decreasing V
REF
, the Input Range of the
ADS7816 Decreases One for One. The effective
resolution remains at 12 bits, however, com-
pared to a 5V FSR system the virtual accuracy is
improved. The ‘Virtual Resolution’ shown in
this table does not account for noise in the
system, which could reduce the accuracy of the
device (particularly at lower values of V
REF
).

TABLE IV. The Input Range of the ADS7817 is Equal to
Twice of the Reference Voltage. By decreasing
V
REF
, the input range of the ADS7817 decreases
proportionally. The effective resolution remains
at 12 bits. Compared to a 5V FSR system the
virtual accuracy is improved. The ‘Virtual Reso-
lution’ shown in this table does not account for
noise in the system, which could reduce the
accuracy of the device (particularly at lower
values of V
REF
).
