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

Ω 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.

Ω. 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).
