PrF 09/2003 –5– AD5380 POWER REQUIREMENTS AVDD 2.7/3.6 V min/max DVDD 2.7/3.6 V min/max Power Supply Sensitivity 2 ∆Mid Scale/∆ΑV DD - 8 5 dB typ AIDD 0 . 5 mA/Channelmax Outputs Unloaded. Boost Off. XXmA typ AIDD 0.57 mA/Channelmax Outputs Unloaded. Boost On. XXmA typ DIDD 5 mA max VIH = DVDD, VIL = DGND. XXmA typ AIDD (Power Down) 5 uA max DIDD (Power Down) 5 uA max Power Dissipation 1 2 5 mW max Outputs Unloaded. NOTES 1 AD5380-3 is calibrated using an external 1.25V reference. Temperature range is -40°C to +85°C. 2Guaranteed by characterization. Not production tested. 3Accuracy guaranteed from Vout = 10mV to AV DD-50mV 4Default on the AD5380-3 is 1.25V. Programmable to 2.5V via CR12 in the AD5380 control register but operating the AD5380-3 with a 2.5V reference will lead to degraded accuracy specifications and limited input code range. Specifications subject to change without notice.
