Test Multiplexer
This circuit receives the positive and negative outputs out of
the two integrators, together with the outputs from different
parts of the chip. The output is controlled by the fifth
programming word of the communications protocol. This
multiplexes the switch capacitor filter output, the gain control
output as well as the antialias output.
Differential to Single-ended Converter
This signal takes the output of the two integrators (through
the test multiplexer circuit) and provides a signal that is the
sum of the two signals. This technique is used to improve the
noise immunity of the system.
Output Buffer
This output amplifier is the same as the input amplifier used
to interface to the sensors. For test purposes when we look
at the output of the antialias filter, the input amplifiers are in
the power down mode.
