7 / 46 page DAC1282, DAC1282A www.ti.com SBAS490B – DECEMBER 2011 – REVISED MAY 2015 Electrical Characteristics (continued) Minimum and maximum specifications are at TA = –40°C to +85°C. Typical specifications are at TA = +25°C, AVDD = +2.5 V, AVSS = –2.5 V, fCLK = 4.096 MHz, VREF = 5 V, and DVDD = 3.3 V (unless otherwise noted). Refer to Figure 50. DAC1282A supports gains = 1/1, 1/4, and 1/16 only. PARAMETER TEST CONDITIONS MIN TYP MAX UNIT POWER SUPPLY AVSS –2.6 0 V AVDD AVSS + 4.75 AVSS + 5.25 V DVDD 1.65 3.6 V Gain = 1/1, VOUT = 0 V 7.4 8.5 mA(11) AVDD, AVSS current Pulse mode, VOUT = 0 V 7 mA Shutdown 1 10 µA Operating 180 300 µA DVDD current Shutdown(12) 1 10 µA Operating 38 44 mW Power Shutdown(12) 10 85 µW TEMPERATURE RANGE Specified temperature range –40 +85 °C Operating temperature range –50 +125 °C Storage temperature range –65 +150 °C (11) Analog supply current scales with gain as follows: IAVDD and IAVSS = 0.016 × VREF × (44 × Gain + 1) + 3.8 (mA). (12) Digital inputs stopped and maintained at VIH or VIL level. Copyright © 2011–2015, Texas Instruments Incorporated Submit Documentation Feedback 7 Product Folder Links: DAC1282 |
