Test Method
(1) Apply a 1 kHz sine
V
p-p
wave to each input
pin.
V
p-p
(2) In each select
mode, measure an
V
p-p
input amplitude at
which the output
V
p-p
waveform on pin 2
(44) begins to be
V
p-p
distorted.
dB
(1) Apply a 1 kHz,
1.0 V
sine wave
p-p
dB
to each input pin.
dB
(2) In each select
mode, find the gain
dB
between input and
dB
output.
(1) Apply a 1.0 V
p-p
MHz
sine wave to each
input pin.
MHz
(2) In each select
mode, measure a
MHz
frequency at which
the output
MHz
amplitude on pin 2
(44) is 3dB down
from the 1 kHz
MHz
applied level.
(1) Apply a 1 kHz,
dB
1.0 V
sine wave
p-p
to each input pin.
dB
(2) In each select
mode, compare
dB
signal output from
the selected pin
dB
with leakage
components from
nonselected pins
dB
to find a crosstalk.
(1) Apply a 1 kHz,
dB
1.0 V
sine wave
p-p
to each input pin.
dB
(2) In each select
mode, compare
dB
the output
amplitudes on pin
dB
2 (44) when mute
is turned on and
turned off to find
dB
mute attenuation.
While applying a 1 kHz
sine wave to pin 5
(47), measure an input
V
amplitude at which the
p-p
output waveform on
pin 40 (40) begins to
be distorted.
