Pre-Production
Stereo Playback to Headphones - DAC input to HPOUTL+HPOUTR pins with 30Ω load.
Test conditions
DACBIAS_SEL = 01b (Normal bias x 0.5)
DACVMID_BIAS_SEL = 11b (Normal bias x 0.75)
PGA_BIAS = 011b (Normal bias x 0.5)
CP_DYN_PWR = 1b (Charge pump controlled by real-time audio level)
Variant test conditions
Slave mode, 44.1kHz sample rate, quiescent
Master mode, 44.1kHz sample rate, quiescent
Master mode, 44.1kHz, P
Master mode, 44.1kHz, P
Master mode, 8kHz sample rate, quiescent
Master mode, 8kHz, P
Stereo Playback to Line-out - DAC input to LINEOUTL+LINEOUTR or HPOUTL+HPOUTR pins with 3.01kΩ / 50pF load
Test conditions:
CP_DYN_PWR = 1b (Charge pump controlled by real-time audio level)
Variant test conditions
44.1kHz sample rate
8kHz sample rate
Stereo analogue bypass to headphones - IN1L/R, IN2L/R or IN3L/R pins to HPOUTL+HPOUTR pins with 30Ω load.
Test conditions: Audio interface disabled
Note that the Analogue bypass configuration does not benefit from the Class W dynamic control, and the power consumption is
greater in this case than the DAC to Line-Out case. See “Charge Pump” section.
