15-Bit, 65Msps ADC with -78.2dBFS
Noise Floor for IF Applications
ELECTRICAL CHARACTERISTICS (continued)
(AVCC = 5V, DVCC = DRVCC = 2.5V, GND = 0, INP and INN driven differentially with -2dBFS, CLKP and CLKN driven differentially
with a 2VP-P sinusoidal input signal, CL = 5pF at digital outputs, fCLK = 65MHz, TA = TMIN to TMAX, unless otherwise noted. Typical
values are at TA = +25°C, unless otherwise noted. â¥+25°C guaranteed by production test, <+25°C guaranteed by design and char-
acterization.)
