1 To simplify terminology throughout this data sheet, because the two amplifiers inside the ADA4351-2 are interchangeable, RF1, RF0, SW0, SW1, SW SEL, +IN, and −IN

refer to Channel A or Channel B. VOUT refers to OUTA or OUTB, and within each channel, RF refers to RF1 or RF0.

2 High speed production testing limits the accuracy of this specification.

3 Linear current is the current that these pins can conduct while VOS shifts by less than 20 μV.
