ELECTRICAL CHARACTERISTICS (continued)
(PVDD = SVDD = 3V, PGND = SGND = 0V, SHDNL = SHDNR = SVDD, C1 = C2 = 2.2F, CIN = 1F, RL =
∞, TA = TMIN to TMAX,
unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)
Note 1: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.
Note 2: Inputs are connected directly to GND.
Note 3: Inputs are AC-coupled to ground.
