15-Bit, 65Msps ADC with -79.3dBFS
Noise Floor for Baseband Applications
Typical Operating Characteristics
(AV_CC = 5V, DV_CC = DRV_CC = 2.5V, INP and INN driven differentially with a -1dBFS amplitude, CLKP and CLKN driven differentially
with a 2V_P-P sinusoidal input signal, C_L = 5pF at digital outputs, f_CLK = 65MHz, T_A = +25°C. All AC data based on a 32k-point FFT
record and under coherent sampling conditions.)
