Figure 2 shows a crosstalk measurement of Left to Right
channel for the gain setting resistors of the headphone
amplifier (referred to as AMP1 and AMP2). The IN2
(output from Codec) and the AMP_OUT2 pin (pins 23
and 25) are driven by a 2Vrms source. The AMP_OUT1
is terminated by a 10K
resistor while the IN1 pin is

terminated with a 1K
resistor which represents the
output impedance of the LINE_OUT output of the Codec.
Pins 5, 7, 22 and 24, on the device are grounded.
Crosstalk measured over the audio band of
20Hz to 20KHz is in excess of –90dB.

Figure 1 shows a cross talk measurement of the micro-
phone to the Right Codec CD signal. The microphone
amplifier output pin (pin 18) is driven with a 2Vrms
signal. The Right CD Codec signal is terminated by a
10K
load resistor while pins 5,7,17 and 22 on the
device are grounded. Crosstalk measured over the audio
band of 20Hz–20KHz is in excess of –90dB.
Channel-to-Channel Crosstalk: Microphone CD
Inter-channel Crosstalk: AMP2-AMP1 (LINE_OUT)
