Note 2: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 3: Supply current measurements taken with no applied signal at microphone inputs. A digital zero audio signal used for all dig-
ital serial audio inputs. Headphone outputs are loaded as stated in the global conditions.
Note 4: DAC performance is measured at headphone outputs.
Note 5: ADC, DAC, and headphone amplifier dynamic ranges are measured using the EIAJ method. -60dBV 1kHz input signal, A-weight-
ed and normalized to 0dBFS.
Note 6: Notch for GSM filters occurs at 217Hz.
