4 / 29 page I/O GND TO INTERNAL CIRCUITRY DAC104S085 SNAS362E – MAY 2006 – REVISED OCTOBER 2012 www.ti.com Operating Ratings (1) (2) Operating Temperature Range −40°C ≤ TA ≤ +125°C Supply Voltage, VA +2.7V to 5.5V Reference Voltage, VREFIN +1.0V to VA Digital Input Voltage(3) 0.0V to 5.5V Output Load 0 to 1500 pF SCLK Frequency Up to 40 MHz (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the maximum Operating Ratings is not recommended. (2) All voltages are measured with respect to GND = 0V, unless otherwise specified. (3) The inputs are protected as shown below. Input voltage magnitudes up to 5.5V, regardless of VA, will not cause errors in the conversion result. For example, if VA is 3V, the digital input pins can be driven with a 5V logic device. Package Thermal Resistances (1) Package θJA 10-Lead VSSOP 240°C/W 10-Lead SON 250°C/W (1) Soldering process must comply with National Semiconductor's Reflow Temperature Profile specifications. Refer to www.national.com/packaging Reflow temperature profiles are different for lead-free packages. Electrical Characteristics The following specifications apply for VA = +2.7V to +5.5V, VREFIN = VA, CL = 200 pF to GND, fSCLK = 30 MHz, input code range 12 to 1011. Boldface limits apply for TMIN ≤ TA ≤ TMAX and all other limits are at TA = 25°C, unless otherwise specified.
