trimmed to 2.42V. It is internally connected to the DAC and
is available at Pin 3 to provide up to 1mA of current to an
external load. For minimum code transition noise, the
reference output should be decoupled with a capacitor to
filter wideband noise from the reference (10
μ
F tantalum in
parallel with a 0.1
μ
F ceramic). The V
REF
pin can be driven
with a DAC or other means to provide input span adjust-
ment in bipolar mode. The V
REF
pin must be driven to at
least 2.45V to prevent conflict with the internal reference.
The reference should not be driven to more than 5V.
Figure 6 shows an LT1306 op amp driving the reference
pin. Figure 7 shows a typical reference, the LT1019A-5
connected to the LTC1360. This will provide an improved
drift (equal to the maximum 5ppm/
°
C of the LT1019A-5)
and a
±
4.231V full scale. If V
REF
is forced lower than
2.42V, the REFRDY bit in the serial data output will be
forced to low.

UNIPOLAR/BIPOLAR OPERATION AND ADJUSTMENT
Figure 8 shows the ideal input/output characteristics for
the LTC1400. The code transitions occur midway between
successive integer LSB values (i.e., 0.5LSB, 1.5LSB,
2.5LSB, … FS – 1.5LSB). The output code is natural binary
with 1LSB = 4.096/4096 = 1mV. Figure 9 shows the
input/output transfer characteristics for the bipolar mode
in two’s complement format.

Unipolar Offset and Full-Scale Error Adjustments
In applications where absolute accuracy is important,
offset and full-scale errors can be adjusted to zero. Figure
