12-Bit, 60Msps, +3.3V, Low-Power ADC
with Internal Reference
ELECTRICAL CHARACTERISTICS (continued)
(V_AVDD = V_DVDD = +3.3V, AGND = DGND = 0, V_IN = ±1.024V, differential input voltage at -0.5dB FS, internal reference, f_CLK =
62.5MHz (50% duty cycle), digital output load C_L ≈ 10pF, T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at
T_A = +25°C.)
