3 / 10 page 259 SPECIFICATIONS (continued) V DD = +5V, All VINX= +0V, VREFL = 1.625, TA = 25° C for commercial–grade parts; T MIN ≤ TA = T MAX for industrial–grade parts; specifications apply to all DAC's unless noted otherwise.) PARAMETER MIN. TYP. MAX. UNIT CONDITIONS DAC OUTPUTS Voltage Range 0 V DD – 1.5 V R L = 5kΩ, VDD = 4.75V Output Current ±10 ±15 mA Note 7 Capacitive Load 47,000 pF No Oscillation DIGITAL OUTPUT Logic High 3.5 V I OH = –0.4mA Logic Low 0.4 V I OL = 1.5mA POWER REQUIREMENTS Power Supply Range 4.75 5.00 5.25 V To rated specifications Positive Supply Current 14 mA PR = LOW Power Dissipation 70 mW PR = LOW ENVIRONMENTAL AND MECHANICAL Operating Temperature Range Commercial 0 +70 °C Industrial –40 +85 °C Storage Temperature Range –65 +150 °C Package SP9840N 24–pin, 0.3" Plastic DIP SP9840S 24–pin 0.3" SOIC SP9843S 20–pin, 0.3" SOIC Note 8 Notes: 1. Code dependent 2. All V IN(x) = GND; D = 55H 3. Offset binary refers to the output voltage with respect to the signal ground at V REFL. For a positive V IN(x), the output will increase from negative fullscale to VREFL to positive (fullscale–1 LSB) as the input code is incremented from 0 to 128 to 255. Note that when V IN(x) is tied to ground and VREFL is driven to +1.625V, as in the production tests above, then the resulting DC at V OUT(x) will decrease from +2V REFL to VREFL/128 as the code is increased from 00H to FFH, due to the VIN(x) input being tied negative with respect to V REFL. 4. The op amp limits linearity for V OUT <100mV. When VIN(x) is driven above ground such that the output voltage remains above 100mV, then the linearity specifications apply to all codes. For V REFL=1.625V, and VIN(x)=GND, codes 248 through 255 are not included in differential or integral linearity tests. Integral and differential linearity are computed with respect to the best fit straight line through codes 0 through 248. 5. SP9840 is measured between adjacent channels, F=100kHz. SP9843 is measured between adjacent pairs, F=100kHz. 6. SP9843 only; measured between channels with shared input; D = 7F H to 80H 7. ∆V OUT < 10mV, VREFL = 1.625V, PR = LOW. 8.
