ELECTRICAL CHARACTERISTICS (continued)
(VCC = 5V, VGND = 0V, MAX9925/MAX9927 gain setting = 1V/V, Mode A1, VBIAS = 2.5V, VPULLUP = 5V, RPULLUP = 1kΩ, CCOUT =
50pF. TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)
Note 2: Specifications are 100% tested at TA = +125°C, unless otherwise noted. All temperature limits are guaranteed by design.
Note 3: Inferred from functional PSRR.
Note 4: CMOS inputs.
Note 5: Guaranteed by design.
Note 6: Includes effect of VOS of internal op amp and comparator.
