PARAMETER TEST CONDITIONS MIN TYP MAX UNIT ANALOG BYPASS TO HEADPHONE AMPLIFIER, DIRECT MODE Load = 16 Ω (single-ended), 50pF; Input and Output CM=0.9V; Device Setup Headphone Output on LDOIN Supply; IN1L routed to HPL and IN1R routed to HPR; Channel Gain=0dB Gain Error –0.8 dB Noise, A-weighted(1) Idle Channel, IN1L and IN1R ac-shorted to ground 3 µV RMS THD Total Harmonic Distortion 446mVrms, 1-kHz input signal –89 dB ANALOG BYPASS TO LINE-OUT AMPLIFIER, PGA MODE Load = 10KOhm (single-ended), 56pF; Input and Output CM=0.9V; LINE Output on LDOIN Supply; Device Setup IN1L routed to ADCPGA_L and IN1R routed to ADCPGA_R; Rin = 20k ADCPGA_L routed to LOL and ADCPGA_R routed to LOR; Channel Gain = 0dB Gain Error 0.6 dB Idle Channel, 7 µV RMS IN1L and IN1R ac-shorted to ground Noise, A-weighted(1) Channel Gain=40dB, 3.4 µV RMS Input Signal (0dB) = 5mVrms Inputs ac-shorted to ground, Input Referred MICROPHONE BIAS Bias voltage Bias voltage CM=0.9V, LDOin = 3.3V Micbias Mode 0, Connect to AVdd or LDOin 1.25 V Micbias Mode 1, Connect to LDOin 1.7 V Micbias Mode 2, Connect to LDOin 2.5 V Micbias Mode 3, Connect to AVdd AVdd V Micbias Mode 3, Connect to LDOin LDOin V CM=0.75V, LDOin = 3.3V Micbias Mode 0, Connect to AVdd or LDOin 1.04 V Micbias Mode 1, Connect to AVdd or LDOin 1.425 V Micbias Mode 2, Connect to LDOin 2.075 V Micbias Mode 3, Connect to AVdd AVdd V Micbias Mode 3, Connect to LDOin LDOin V Output Noise CM=0.9V, Micbias Mode 2, A-weighted, 20Hz to 10 20kHz bandwidth, µV RMS Current load = 0mA. Current Sourcing Micbias Mode 2, Connect to LDOin 3 mA Micbias Mode 3, Connect to AVdd 140 Inline Resistance Ω Micbias Mode 3, Connect to LDOin 87 (1) All performance measurements done with 20-kHz low-pass filter and, where noted, A-weighted filter. Failure to use such a filter may result in higher THD+N and lower SNR and dynamic range readings than shown in the Electrical Characteristics. The low-pass filter removes out-of-band noise, which, although not audible, may affect dynamic specification values Submit Documentation Feedback Electrical Specifications 9 |
