Note 1: Specifications ≥+25°C guaranteed by production test, <+25°C guaranteed by design and characterization.
Note 2: SNR, SINAD, SFDR, HD3, and THD are based on a differential analog input voltage of -0.5dB FS referenced to the
Note 3: The power consumption of the output driver is proportional to the load capacitance (C L ).
Note 4: Guaranteed by design and characterization. Not production tested.
Note 5: SINAD settles to within 0.5dB of its typical value.
Note 6: Crosstalk rejection is measured by applying a high-frequency test tone to one channel and a low-frequency tone to the
Note 7: Amplitude/phase matching is measured by applying the same signal to each channel, and comparing the magnitude and
