150ksps, 10-Bit, 2-Channel Single-Ended, and
1-Channel True-Differential ADCs in SOT23
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +2.7V to +3.6V, VREF = +2.5V for MAX1087/MAX1089, or VDD = +4.75V to +5.25V, VREF = +4.096V for MAX1086/MAX1088,
0.1µF capacitor at REF, fSCLK = 8MHz (50% duty cycle), AIN- = GND for MAX1088/MAX1089. TA = TMIN to TMAX, unless otherwise
noted. Typical values at TA = +25°C.)
