ELECTRICAL CHARACTERISTICS (continued)

(VPVIN = 1.8V, VPGND = VGND = 0V, VSHDN = 1.8V, C1 = C2 = C3 = 1FF, C4 = 10FF, TA = TMIN to TMAX, unless otherwise noted.

Typical values are at TA = +25NC) (Note 2)

Note 2: All specifications are 100% tested at TA = +25NC. Temperature limits are guaranteed by design.

Note 3: VPVDD = 0.9V, VPVSS = -0.9V.

Note 4: VPVDD = 1.8V, VPVSS = -1.8V.

Typical Operating Characteristics

(VPVIN = 1.8V, VPGND = VGND = 0V, VSHDN = 1.8V, C1 = C2 = C3 = 1FF, C4 = 10FF, both channels driven in phase, TA = +25NC,

unless otherwise noted.)
