ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C (Note 2). VCC = VDD = OVDD = 3.3V, VREF = 1.8V, EN = 3.3V, fSMPL =
fSMPL(MAX) and fSCK = fSCK(MAX) unless otherwise noted. Test circuit is shown in Figure 1.
