Note 2: The MAX98090 is 100% production tested at T
Note 3: BIAS derived from a bandgap reference (BIAS_MODE = 1).
Note 4: Analog supply current = AVDD + HPVDD, speaker supply current = SPKLVDD + SPKRVDD, and digital supply current =
Note 5: Dynamic range measurements are performed with the EIAJ method (a -60dBFS output signal at 1kHz, A-weighted and nor-
Note 6: Gain measured relative to the 0dB setting.
Note 7: Performance measured using DAC Inputs, unless otherwise stated.
Note 8: Full-scale analog output with 0dB of programmable gain, and a 0dBFS DAC input amplitude, a 1V
Note 9: Performance measured using an analog input to amplifier output path.
Note 10: Digital filter performance is invariant over temperature and production tested at T
Note 11: The filter specification is accurate only for synchronous clocking modes (integer MCLK to LRCLK ratio).
Note 12: f
Note 13: In master-mode operation, the accuracy of the MCLK input proportionally determines the accuracy of the sample clock rate.
