7 / 35 page DAC128S085 www.ti.com SNAS407H – AUGUST 2007 – REVISED APRIL 2015 Electrical Characteristics (continued) The following specifications apply for VA = 2.7 V to 5.5 V, VREF1 = VREF2 = VA, CL = 200 pF to GND, fSCLK = 30 MHz, input code range 48 to 4047. All limits are at TA = 25°C, unless otherwise specified. PARAMETER TEST CONDITIONS MIN(1) TYP MAX(1) UNIT VA = 3 V, VOUT = 0 V, −50 mA Input Code = FFFh Output Short Circuit Current IOS (source)(3) VA = 5 V, VOUT = 0 V, −60 mA Input Code = FFFh VA = 3 V, VOUT = 3 V, 50 mA Input Code = 000h Output Short Circuit Current IOS (sink)(3) VA = 5 V, VOUT = 5 V, 70 mA Input Code = 000h TA = 105°C 10 mA TMIN ≤ TA ≤ TMAX Continuous Output Current per IO channel(2) TA = 125°C 6.5 mA TMIN ≤ TA ≤ TMAX RL = ∞ 1500 pF CL Maximum Load Capacitance RL = 2 kΩ 1500 pF ZOUT DC Output Impedance 8 Ω REFERENCE INPUT CHARACTERISTICS 0.5 Input Range Minimum V TMIN ≤ TA ≤ TMAX 2.7 VREF1,2 Input Range Maximum TMIN ≤ TA ≤ TMAX VA V Input Impedance 30 k Ω LOGIC INPUT CHARACTERISTICS IIN Input Current(2) TMIN ≤ TA ≤ TMAX ±1 µA VA = 2.7 V to 3.6 V 1 V TMIN ≤ TA ≤ TMAX 0.6 VIL Input Low Voltage VA = 4.5 V to 5.5 V 1.1 V 0.8 VA = 2.7 V to 3.6 V 1.4 V TMIN ≤ TA ≤ TMAX 2.1 VIH Input High Voltage VA = 4.5 V to 5.5 V 2 V TMIN ≤ TA ≤ TMAX 2.4 CIN Input Capacitance(2) TMIN ≤ TA ≤ TMAX 3 pF (3) This parameter does not represent a condition which the DAC can sustain continuously. See the continuous output current specification for the maximum DAC output current per channel.
