12-Bit, 60Msps, +3.3V, Low-Power ADC
with Internal Reference
Typical Operating Characteristics (continued)
(V_AVDD = V_DVDD = +3.3V, AGND = DGND = 0, V_IN = ±1.024V, differential input voltage at -0.5dB FS, f_CLK = 60.006MHz (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.)
