3 / 16 page  3 ® DAC902 POWER SUPPLY Supply Voltages +VA +2.7 +5 +5.5 V +VD +2.7 +5 +5.5 V Supply Current(6) IVA 24 30 mA IVA, Power-Down Mode 1.1 2 mA IVD 815 mA Power Dissipation +5V, IOUT = 20mA 170 230 mW +3V, IOUT = 2mA 50 mW Power Dissipation, Power-Down Mode 45 mW Thermal Resistance, θ JA SO-28 75 °C/W TSSOP-28 50 °C/W NOTES: (1) At output IOUT, while driving a virtual ground. (2) Measured single-ended into 50Ω Load. (3) Nominal full-scale output current is 32 • IREF; see Application Section for details. (4) Reference bandwidth depends on size of external capacitor at the BW pin and signal level. (5) Typically 45 µA for the PD pin, which has an internal pull-down resistor. (6) Measured at fCLOCK = 50MSPS and fOUT = 1.0MHz. DAC902U/E PARAMETER CONDITIONS MIN TYP MAX UNITS SPECIFICATIONS (Cont.) At TA = full specified temperature range, +VA = +5V, +VD = +5V, differential transformer coupled output, 50Ω doubly terminated, unless otherwise specified. ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degrada- tion to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
