OUTPUT ADJUSTMENT
The REF05 trim terminal can be used to adjust the voltage
over a 5V
±
150mV range. This feature allows the system
designer to trim system errors by setting the reference to a
voltage other than 5V, including 5.12V
(1)
for binary applica-
tions (see Figure 1).

2.5V Precision Reference.
FIGURE 6. Current Sink.
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature
coefficient change is approximately 0.7ppm/
°
C for 100mV of
output adjustment.
NOTE: (1) 20mV LSB for 8-bit applications.
