Low-Power Comparators with Precision

Reference in 4-Bump UCSP

_______________________________________________________________________________________

3

Note 1: All devices are 100% production tested at TA = +25°C. Temperature limits are guaranteed by design.

Note 2: Too small to be measured in an ATE test environment. Only gross test to catch failures is implemented.

Note 3: Overdrive is defined as the voltage above or below the switching points.

Note 4: Guaranteed by ATE and/or bench characterization over temperature. VREF is the average of the trip points.

Note 5: Hysteresis is half the input voltage difference between the two switching points.

Note 6: Includes reference error along with comparator offset voltage error.

ELECTRICAL CHARACTERISTICS

(VCC = 3.3V, RPULLUP = 10kΩ to VPULLUP = 3.3V for MAX9644/MAX9645, TA = -40°C to +85°C. Typical values at TA = +25°C, unless

otherwise noted.) (Note 1)
