15-Bit, 80Msps ADC with -78.4dBFS
Noise Floor for IF Applications
Typical Operating Characteristics (continued)
(AV_CC = 5V, DV_CC = DRV_CC = 2.5V, INP and INN driven differentially with a -2dBFS amplitude, CLKP and CLKN driven differentially
with a 2V_P-P sinusoidal input signal, C_L = 5pF at digital outputs, f_CLK = 80MHz, T_A = 25°C. All AC is data based on a 32k-point FFT
record and under coherent sampling conditions.)
