ADC12D1000, ADC12D1600 www.ti.com SNAS480N – MAY 2010 – REVISED AUGUST 2015 6.5 Electrical Characteristics: Static Converter Unless otherwise specified, the following apply after calibration for VA = VDR = VTC = VE = 1.9 V; 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 = 1 or 1.6 GHz 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 = 100-Ω Differential; 1:2 Demultiplex Non-DES Mode; Duty Cycle Stabilizer on. All other limits TA = 25°C, unless otherwise noted.

Input voltage magnitudes beyond the Absolute Maximum Ratings may (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 ensured 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 8. 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.
