Dual 10-Bit, 105Msps, 3.3V, Low-Power ADC with Internal Reference and Parallel Outputs

Maxim Integrated 

Dual 10-Bit, 105Msps, 3.3V, Low-Power ADC

with Internal Reference and Parallel Outputs

ELECTRICAL CHARACTERISTICS (continued)

(VDD = 3.3V, OVDD = 2.5V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND; REFOUT connected to REFIN through a

10kΩ resistor, VIN = 2VP-P (differential with respect to COM), CL = 10pF at digital outputs (Note 1), fCLK = 105.263MHz, TA = TMIN to

TMAX, unless otherwise noted. Typical values are at TA = +25°C.) (Note 2)

Note 1: Equivalent dynamic performance is obtainable over full OVDD range with reduced CL.

Note 2: Specifications at ≥ +25°C are guaranteed by production test and < +25°C are guaranteed by design and characterization.

Note 3: SNR, SINAD, THD, SFDR, and HD3 are based on an analog input voltage of -0.5dBFS, referenced to a 1.024V full-scale

input voltage range.

Note 4: Intermodulation distortion is the total power of the intermodulation products relative to the individual carrier. This number is

6dB or better, if referenced to the two-tone envelope.

Note 5: Digital outputs settle to VIH, VIL. Parameter guaranteed by design.

Note 6: With REFIN driven externally, REFP, COM, and REFN are left floating while powered down.
