9 / 66 page  DAC5682Z www.ti.com SLLS853F – AUGUST 2007 – REVISED JANUARY 2015 Electrical Characteristics — DC Specification (continued) over operating free-air temperature range , AVDD = 3.3 V, CLKVDD = 1.8 V, IOVDD = 3.3 V, DVDD = 1.8 V, IoutFS = 20 mA (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT AVDD AVDD V Output Compliance range(3) IOUTFS = 20 mA –0.5V + 0.5V Output resistance 300 k Ω Output capacitance 5 pF REFERENCE OUTPUT Vref Reference voltage 1.14 1.2 1.26 V Reference output current(4) 100 nA REFERENCE INPUT VEXTIO Input voltage range 0.1 1.25 V Input resistance 1 M Ω CONFIG6: BiasLPF_A and BiasLPF_B = 0 95 Small signal bandwidth kHz CONFIG6: BiasLPF_A and BiasLPF_B = 1 472 Input capacitance 100 pF TEMPERATURE COEFFICIENTS ppm of Offset drift ±1 FSR/°C With external reference ±15 ppm of Gain drift FSR/°C With internal reference ±30 Reference voltage drift ±8 ppm/°C POWER SUPPLY Analog supply voltage, AVDD 3.0 3.3 3.6 V Digital supply voltage, DVDD 1.7 1.8 1.9 V Clock supply voltage, CLKVDD 1.7 1.8 1.9 V I/O supply voltage, IOVDD 3.0 3.3 3.6 V I(AVDD) Analog supply current 133 mA I(DVDD) Digital supply current 455 mA Mode 4 (below) I(CLKVDD) Clock supply current 45 mA I(IOVDD) IO supply current 12 mA I(AVDD) Sleep mode, AVDD supply current 1.0 mA I(DVDD) Sleep mode, DVDD supply current 1.5 mA Mode 6 (below) Sleep mode, CLKVDD supply I(CLKVDD) 2.5 mA current I(IOVDD) Sleep mode, IOVDD supply current 2.0 mA (3) The lower limit of the output compliance is determined by the CMOS process. Exceeding this limit may result in transistor breakdown, resulting in reduced reliability of the DAC5682Z device. The upper limit of the output compliance is determined by the load resistors and full-scale output current. Exceeding the upper limit adversely affects distortion performance and integral nonlinearity. (4) Use an external buffer amplifier with high impedance input to drive any external load.
