Note 1: Temp = 25°C, VA = VD = REF+ = 5V, Fs = 48kHz, FINPUT = 1kHz, Bandwidth = 20Hz-20kHz.

Note 2: Full scale input scales linearly with REF potential ([REF+]-[REF-]).

Note 3: REF current scales linearly with Fs.

Note 4: Temp = 25°C, VA = VD = REF+ = 5V, Fs = 48kHz, FINPUT = 1kHz.

Note 5: Passband, stopband, and highpass frequencies scale with Fs.

Note 6: Passband is compensated for an external single-pole 80kHz lowpass filter at analog inputs (0.26dB

at 20kHz). Compensation scales with Fs.
