10-Bit, 60Msps, 3.0V, Low-Power
ADC with Internal Reference
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 3.0V, OVDD = 2.7V; 0.1µF and 1.0µF capacitors from REFP, REFN, and COM to GND; VREFIN = 2.048V, REFOUT connected
to REFIN through a 10kΩ resistor, VIN = 2VP-P (differential with respect to COM), CL â 10pF at digital outputs, fCLK = 62.5MHz
(50% duty cycle), TA = TMIN to TMAX, unless otherwise noted. â¥+25°C guaranteed by production test, < +25°C guaranteed by design
and characterization. Typical values are at TA = +25°C.)
