3 / 16 page +2.5V to +5.5V, Low-Power, Single/Dual, 8-Bit Voltage-Output DACs in µMAX Package _______________________________________________________________________________________ 3 ELECTRICAL CHARACTERISTICS (continued) (VDD = +2.5V to +5.5V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at TA = +25°C) TIMING CHARACTERISTICS (VDD = +2.5V to +5.5V, TA = TMIN to TMAX, unless otherwise noted. Digital inputs switching from 0V to VDD.) (Figure 3) (Note 4) Note 1: Cold temperature specifications (to -40°C) guaranteed by design using six sigma design limits. Note 2: Worst-case input resistance at REF occurs at DAC code 55 hex. Note 3: Worst-case reference input current occurs at DAC code 55 hex. Note 4: Guaranteed by design. Not production tested. Note 5: IDD measured with DACs loaded with worst-case DAC code 55 hex.
