Crosstalk is measured at 70 MHz with −1.0 dBFS analog input on one channel and no input on the adjacent channel.
Overrange condition is specified with 3 dB of the full-scale input range.
PSRR is measured by injecting a sinusoidal signal at 10 MHz to the power supply pin and measuring the output spur on the FFT. PSRR is calculated as the ratio of the
amplitudes of the spur voltage over the pin voltage, expressed in decibels.
