11 / 59 page ADC08D1520QML-SP www.ti.com SNAS420O – JANUARY 2008 – REVISED MARCH 2013 ADC08D1520 Converter Electrical Characteristics DC Parameters (1) (continued) The following specifications apply after calibration for VA = VDR = +1.9V; OutV = 1.9V; VIN FSR (a.c. coupled) = differential 870 mVP-P; CL = 10 pF; Differential, a.c. coupled Sine Wave Input Clock, fCLK = 1.5 GHz at 0.5 VP-P with 50% duty cycle; VBG = Floating; Non-Extended Control Mode; SDR Mode; REXT = 3300 Ω ±0.1%; Analog Signal Source Impedance = 100 Ω Differential; 1:2 Output Demultiplex, duty cycle stabilizer on. Boldface limits apply for TA = TMIN to TMAX. All other limits TA = 25°C, unless otherwise noted.

Full-Scale Error for this device, therefore, is a combination of Full-Scale Error and Reference Voltage Error. See Figure 3. For relationship between Gain Error and Full-Scale Error, see Specification Definitions for Gain Error. (6) This parameter is ensured by design and/or characterization and is not tested in production. (7) The analog and clock input capacitances are die capacitances only. Additional package capacitances of 0.65 pF differential and 0.95 pF each pin to ground are isolated from the die capacitances by lead and bond wire inductances.
