Notes
1.
A sine wave rms level applied differentially between the microphone pins. The A/D path gain in Control Register 2 is
set to +9 dB. For larger input levels the output signal will saturate.
A sine wave rms level applied differentially between pins LIFP_ADn and LIFM_ADn (n = 1 for Codec 1; n = 2 for
Codec 2). The A/D path gain is set to +9 dB using Control Register 2. For larger input levels the output signal will
saturate.
Valid for Codec 1 and Codec 2. Control Register 0 = 0003H (Codec 1) or 0018H (Codec 2) and the A/D path gain in
Control Register 2 is set to +9 dB. The microphone pins are shorted together. The value is psophometrically
weighted.
Valid for Codec 1 and Codec 2. Control Register 0 = 0003H (Codec 1) or 0018H (Codec 2) and the A/D path gain in
Control Register 2 is set to +9 dB. A sine wave of 1030 Hz is applied between the microphone input pins. The value
is psophometrically weighted and includes harmonic distortion.
Valid for Codec 1 and Codec 2. G
AD
is the A/D gain value selected in Control Register 2. The gain is measured at
1030 Hz from the LIF interface (pins LIFP_ADn and LIFM_ADn, where n = 1 for Codec 1 and n = 2 for Codec 2) to
the PCM interface.
The difference between two adjacent gain settings as specified in Control Register 2. Valid for Codec 1 and Codec 2.
Valid for Codec 1 and Codec 2. G
DA
is the D/A gain value selected in Control Register 2. The gain is measured at
970 Hz, from the PCM interface to the LIF interface (pins LIFP_DA1 and LIFM_DA1, for Codec 1 and pins EARP_HS
and EARM_HS for Codec 2).
Valid for Codec 1 and Codec 2. Sine wave rms level differentially seen between pins LIFP_DA1 and LIFM_DA1
(Codec 1) or EARP_HS and EARM_HS (Codec 2), with an input signal of 970 Hz and a level of +3.14 dBm0 at the
PCM interface. Load resistance is larger than 120
. The D/A path gain in Control Register 2 is set to +2 dB.
Valid for Codec 1 and Codec 2. Control Register 0 = 0003H (Codec 1) or 0018H (Codec 2). The D/A path gain in
Control Register 2 is set to 0 dB and the DSP is set to idle mode. The value is psophometrically weighted.
10. Valid for Codec 1 and Codec 2. Control Register 0 = 0003H (Codec 1) or 0018H (Codec 2).The D/A path gain in
Control Register 2 is set to 0 dB. A sine wave of 970 Hz is applied. The value is psophometrically weighted and
includes harmonic distortion.
11. The D/A path is loaded with (150
+ 800
μ
F)//100 pF.
