Note 1: Input switch crosstalk measurement method:
(pin 19 = “H” or open, pin 26 = GND, pin 27 = 0.733
×
pin 4, pin 28 = 0.80
×
pin 4, pin 29 = 2.2V, pin 30 = 2.2V)
Input 1kHz signals on the INT input pins (3 and 46) in INT input mode that give a distortion of 1% at the signal output pins (17 and 32), then
connect the EXT input pins (5 and 44) to GND via R
g
= 1k
Switch to EXT input mode, and measure the relative output level of the output pins
(17 and 32).
Note 2: Interchannel crosstalk measurement method:
The mode pin conditions are the same as for input switch crosstalk.
Connect the input pin of the channel to be measured to GND via R
g
= 1k
. Input a 1kHz signal on the other channel's input that gives a distortion
of 1% on the signal output pins (17 and 32), and measure the relative output level between the signal output pins (17 and 32).
