Note 2:
The analog outputs can swing to within 2.5V of the supply rails. Hence, for good linearity towards full-scale, |V
REFA
|and |V
REFB
|must
be at least 2.5V lower than V

| Tests done with supply voltages below ±12.5V are done with V

Note 3:
Static performance tested at V

= -15V. Performance over supplies guaranteed by PSRR test.
Note 4:
Guaranteed by design.
