ELECTRICAL CHARACTERISTICS—B Grade (1% Initial Accuracy) (continued)

(VCC = 5V, VEE = 0V, VCM = 0V, IOUT = 0A, IREF = 0A, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C.)

(Note 2)

Note 2: All devices are 100% production tested at TA = +25°C. Limits over the extended temperature range are guaranteed by

design.

Note 3: Supply voltage range guaranteed by PSRR test on comparator and line regulation of REF.

Note 4: VOS is defined as the center of the input-referred hysteresis band.

Note 5: For the comparators with the inverting input (IN-) uncommitted.

Note 6: Input bias current is the average of the inverting and noninverting input bias currents.

Note 7: Not production tested. Guaranteed by design.

Note 8: Guaranteed by CMRR test.

Note 9: VOVERDRIVE is beyond the offset and hysteresis determined trip point.

Note 10: Temperature coefficient is measured by the box method; i.e., the maximum

ΔVREF is divided by the maximum ΔT.

Note 11: Thermal hysteresis is defined as the change in VREF at +25°C before and after cycling the device from TMIN to TMAX.
