NOTE 3: The input signal is a 1020 Hz-sine wave for the ADC channel. Harmonic distortion is defined for an input level
of – 1 dB.

NOTE 4: The input signal is the digital equivalent of a 1020-Hz sine wave (digital full scale = 0 dB). The nominal
differential DAC channel output with this input condition is 6 V peak to peak. The load impedance for the DAC
output buffer is 600 Ω from OUT + to OUT –. Harmonic distortion is specified for a signal input level of 0 dB.
