Note 2: The analog outputs can swing to within 2.5V of the supply rails. Hence, for good linearity towards full-scale, |VREFA| and |VREFB| must
be at least 2.5V lower than VDD and |VSS|. Tests done with supply voltages below ±12.5V are done with VREFA = VREFB = ±8.9V.
Note 3: Static performance tested at VDD = +15V, VSS = -15V. Performance over supplies guaranteed by PSRR test.
Note 4: Guaranteed by design.
