ELECTRICAL CHARACTERISTICS (continued)
(V DD = +2.7V to +3.6V, V REF = +2.5V for MAX1087/MAX1089, or V DD = +4.75V to +5.25V, V REF = +4.096V for MAX1086/MAX1088,
0.1µF capacitor at REF, f SCLK = 8MHz (50% duty cycle), AIN- = GND for MAX1088/MAX1089. T A = T MIN to T MAX, unless otherwise
noted. Typical values at T A = +25°C.)
