Note:

To maintain specified linearity, the external amplifier

(A) must be nulled. Apply an ‘all zeroes’ digital input and

adjust ROS for VOUT = 0 +/- 1mv.

Note:

To maintain specified linearity, the external amplifier (A1

and A2) must be nulled. With a digital input of 10...0 and

VREF set to zero:

a) set ROS1 for VO1 =0, b) set ROS2 for VOUT = 0

c) set VREF to +10v and adjust Rb for VOUT to be 0

volts.
