Note 1: Devices 100% production tested at TA = +125°C. Guaranteed by design and characterization to TA = -40°C.
Note 2: Full scale in analog EQ mode decreases with increasing frequency at a rate of 20dB/decade from 8kHz. If digital EQ is also
used, full scale decreases with increasing frequency at 40dB/decade from 5kHz.
Note 3: SFDR in the EQ mode is normalized to the input by subtracting the analog EQ gain at each frequency (20dB/decade) from
the FFT results.
Note 4: The absolute input voltage range is 0 to AVDD. For optimal performance, use a common-mode voltage of AVDD/2.
Note 5: Switched capacitor input impedance is proportional to 1/fC. Where f is the sampling frequency and C is the input capacitance.
