TIMING CHARACTERISTICS (continued)

(MAX7651: AVDD = VPWMV = DVDD = VREF+ = +4.5 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.) (Figure 3)
