ELECTRICAL CHARACTERISTICS (continued)
(VCC = SVCC = +5V, RL = ∞ on all outputs, CBYPASS = 1F, CBIAS = 1F, CREG = 10F (MAX4299), TA = TMIN to TMAX, unless other-
wise noted. Load resistors (RL) are terminated to 2.25V. Typical values are at TA = +25°C. Specifications apply to both MAX4298 and
MAX4299, unless otherwise noted.) (Note 1)
