4 / 28 page DAC102S085 SNAS364E – MAY 2006 – REVISED MARCH 2013 www.ti.com Electrical Characteristics (1) 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.

(2) Typical figures are at TJ = 25°C, and represent most likely parametric norms. Test limits are specified to AOQL (Average Outgoing Quality Level). (3) This parameter is specified by design and/or characterization and is not tested in production. 4 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: DAC102S085 |
