Refer to www.ti.com/packaging(1) (1) Reflow temperature profiles are different for lead-free and non-lead-free packages. 3.4 Converter Electrical Characteristics Static Converter Characteristics Unless otherwise specified, the following apply after calibration for VA = VDR = VTC = VE = +1.9V; I- and Q-channels, AC- coupled, unused channel terminated to AC ground, FSR Pin = High; CL = 10 pF; Differential, AC coupled Sine Wave Sampling Clock, fCLK = 1600/1000 MHz at 0.5 VP-P with 50% duty cycle (as specified); VBG = Floating; Non-Extended Control Mode; Rext = Rtrim = 3300 Ω ± 0.1%; Analog Signal Source Impedance = 100Ω Differential; Non-Demux Non-DES Mode; Duty Cycle Stabilizer on. Boldface limits apply for TA = TMIN to TMAX. All other limits TA = 25°C, unless otherwise noted.

Input voltage magnitudes beyond the Absolute Maximum Ratings may damage this device. (2) To ensure accuracy, it is required that VA, VTC, VE and VDR be well-bypassed. Each supply pin must be decoupled with separate bypass capacitors. (3) Typical figures are at TA = 25°C, and represent most likely parametric norms. Test limits are specified to TI's AOQL (Average Outgoing Quality Level). (4) Calculation of Full-Scale Error for this device assumes that the actual reference voltage is exactly its nominal value. Full-Scale Error for this device, therefore, is a combination of Full-Scale Error and Reference Voltage Error. See Figure 4-2. For relationship between Gain Error and Full-Scale Error, see Specification Definitions for Gain Error. (5) This parameter is specified by design and is not tested in production.
