ELECTRICAL CHARACTERISTICS—MAX6138_41 (4.096V)

(IR = 100µA, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

ELECTRICAL CHARACTERISTICS—MAX6138_50 (5.0V)

(IR = 100µA, TA = -40°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.) (Note 1)

Note 1: All devices are 100% production tested at +25°C and are guaranteed by correlation for TA = TMAX to TMIN, as specified.

Note 2: TC is measured by the “box” method, i.e. (VMAX - VMIN) / (TMAX - TMIN)

Note 3: Guaranteed by design.
