No missing codes at room temperature guaranteed for 105 MSPS grade. 2 Gain error and gain temperature coefficients are based on the ADC only (with a fixed 1.25 V external reference) 65 grade in 2 V p-p range, 40, 80, 105 grades in 1 V p-p range. 3 (AIN –AIN) = ±0.5 V in 1 V range (full scale), (AIN – AIN) = ±1 V in 2 V range (full scale). The analog inputs self-bias to VD/3. This common-mode voltage can be overdriven externally by a low impedance source by ±300 mV (differential drive, gain = 1) or ±150 mV (differential drive, gain = 2). 4 AC power dissipation measured with rated encode and a 10.3 MHz analog input @ 0.5 dBFS, CLOAD = 5 pF. 5 DC power dissipation measured with rated encode and a dc analog input (outputs static, IVDD = 0). 6 In power-down state, IVDD = ±10 μA typical (all grades).
