10-Bit, 80Msps, Single 3.0V, Low-Power
ADC with Internal Reference
ELECTRICAL CHARACTERISTICS (continued)
(V_DD = 3.0V, OV_DD = 2V, 0.1µF and 1µF capacitors from REFP, REFN, and COM to GND, V_REFIN = 2.048V, REFOUT connected to
REFIN through a 10kΩ resistor, V_IN = 2V_P-P (differential with respect to COM), C_L = 10pF at digital outputs, f_CLK = 83.3MHz, T_A = T_MIN
to T_MAX, unless otherwise noted. ≥ +25°C guaranteed by production test, < +25°C guaranteed by design and characterization; typical
values are at T_A = +25°C.)

Note 1: SNR, SINAD, THD, SFDR, and HD3 are based on an analog input voltage of -0.5dB FS referenced to a 1.024V full-scale
input voltage range.
Note 2: Intermodulation distortion is the total power of the intermodulation products relative to the individual carrier. This number is
6dB better if referenced to the two-tone envelope.
Note 3: Digital outputs settle to V_IH,V_IL.
Note 4: With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.
