8 / 44 page AD5390/AD5391/AD5392 Rev. A | Page 8 of 44 Parameter AD5390-31 AD5392-3 1 AD5391-3 1 Unit Test Conditions/Comments Glitch Rejection 50 50 ns max Input filtering suppresses noise spikes <50 ns. Logic Outputs (BUSY, SDO) 2 Output Low Voltage 0.4 0.4 V max DVDD = 2.7 V to 5.5 V, sinking 200 µA. Output High Voltage DVDD − 0.5 DVDD − 0.5 V min DVDD = 2.7 V to 3.6 V, SDO only, sourcing 200 µA. DVDD − 0.1 DVDD − 0.1 V min DVDD = 4.5 V to 5.5 V, SDO only, sourcing 200 µA. High Impedance Leakage Current ±1 ±1 µA max High Impedance Output Capacitance 5 5 pF typ Logic Output (SDA) 2 VOL, Output Low Voltage 0.4 0.4 V max ISINK = 3 mA. 0.6 0.6 V max ISINK = 6 mA. Three-State Leakage Current ±1 ±1 µA max Three-State Output Capacitance 8 8 pF typ POWER REQUIREMENTS AVDD 2.7/3.6 2.7/3.6 V min/max DVDD 2.7/5.5 2.7/5.5 V min/max Power Supply Sensitivity 2 ∆Midscale/∆AVDD −85 −85 dB typ AIDD 0.375 0.375 mA/channel max Outputs unloaded; boost off; 0.25 mA/channel typ. AIDD 0.475 0.475 mA/channel max Outputs unloaded; boost on; 0.325 mA/channel typ. DIDD 1 1 mA max VIH = DVDD, VIL = DGND. AIDD (Power-Down) 1 1 µA max DIDD (Power-Down) 20 20 µA max Power Dissipation 21 21 mW max AD5390/AD5391 with outputs unloaded; AVDD = DVDD = 3 V; boost off. 12 12 mW max AD5392 with outputs unloaded; AVDD = DVDD = 3 V; boost off. 1 AD539x-3 products are calibrated with a 1.25 V reference. Temperature range for all versions: −40°C to +85°C. 2 Guaranteed by characterization, not production tested. 3 Programmable either to 1.25 V typ or 2.5 V typ via the AD539x control register. Operating the AD539x-3 products with a reference of 2.5 V leads to a degradation in performance accuracy. 4 Accuracy guaranteed from VOUT = 39 mV to AVDD − 50 mV. |
