ELECTRICAL CHARACTERISTICS (continued)

(MAX7651 AVDD = VPWMV = DVDD = VREF+ = +4.5V to +5.5V, VREF- = 0, fXTAL = 12MHz. MAX7652 AVDD = VPWMV = DVDD = +2.7V

to +3.6V, VREF+ = +2.5V, VREF- = 0, ACOM = AVDD/2, fXTAL = 12MHz. TA = TMIN to TMAX, unless otherwise noted. Typical values are

at TA = +25°C.)
