Note 1: All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2: Supply current measurements taken with no applied input signal to line and microphone inputs. A digital zero audio signal
used for all digital serial audio inputs. Speaker and headphone outputs are loaded as stated in the global conditions.
Note 3: DAC performance measured at headphone outputs.
Note 4: Dynamic range measured using the EIAJ method. The input is applied at -60dBFS, fIN = 1kHz. The is THD+N referred to
0dBFS.
Note 5: Signal-to-noise ratio measured using an all-zeros input signal, and is relative to 0dB full scale. The DAC is not muted for the
SNR measurement.
Note 6: Performance measured from line inputs (unless otherwise noted).
Note 7: Microphone amplifiers connected to ADC, microphone inputs AC-grounded.
Note 8: In master-mode operation, the accuracy of the MCLK input proportionally determines the accuracy of the sample clock
rate. (VDVDD = 1.8V, unless otherwise noted).
Note 9: To enable the line input, make sure the desired input is selected by either the audio output mixer or the ADC input mixer.
Note 10: CB is in pF.
