ELECTRICAL CHARACTERISTICS (continued)
(V
put load is AC-coupled to differential 100Ω (see Figure 1), typical values are at +25°C, V
otherwise specified. Registers are set to default values unless otherwise noted, and the 3-wire interface is static during measure-
ments. For testing, the MODE_SEL bit was used and the MSEL pin was left open.)
