Functional Description
(Continued)
any output of Port B will source current into node V
thus
raising the voltage at V
and making the output differential
more negative. Conversely, a logic “0” (0V) will pull current
out of node V
and decrease the voltage, causing the differ-
ential output to become more positive. For the resistor val-
ues shown, V
can move
±
12 mV with a resolution of 50 μV,
which will null the offset error term to
1
4
LSB of full-scale for
theADC0801. It is important that the voltage levels that drive
the auto-zero resistors be constant. Also, for symmetry, a
logic swing of 0V to 5V is convenient. To achieve this, a
CMOS buffer is used for the logic output signals of Port B
and this CMOS package is powered with a stable 5V source.
Buffer amplifier A1 is necessary so that it can source or sink
the D/A output current.

Note 26:
R2 = 49.5 R1
Note 27:
Switches are LMC13334 CMOS analog switches.
Note 28:
The 9 resistors used in the auto-zero section can be
±
5% tolerance.
