TEST METHOD
1
Signal A
0 [V]
Pins 8, 9, 10
Measure the output level of each pin (VOUT [mVrms])
2
Signal A
0 [V]
Pins 8, 9
Calculate the output level ratio between pins 8 and 9 (V8, V9).
VOUT [dB] = 20| og
l
(V8 / V9)|
3
Signal B
0 [V]
5 [V]
0 [V]
Pins 8, 9
Raise VCC from 8.1V to 9.9 V and measure the output level
(VV'). Calculate the ratio against the output level (VV) when
VCC = 9V
VSub [dB] = 20|og (VV' / VV)|
4
Signal A
Signal B
Signal C
Signal D
0 [V]
0 / 5 [V]
0 [V]
Pins 8, 9
Set pin 4 to 0 V. Input signal A and measure the output level
(VM1k). Next, input signal C, D and measure its output level at
100 Hz and 10 kHz (VM100 and VM10k).
A100 M [dB] = 20 og (VM100 / VM1k)
A10k M [dB] = 20 og (VM10k / VM1k)
Set pin 4 to 5 V. Input signal B and measure the output level
(VS1k). Next, input signal C, D and measure its output level at
100 Hz and 10 kHz (VS100 and VS10k).
A100 S [dB] = 20 og (VS100 / VS1k)
A10k S [dB] = 20 og (VS10k / VS1k)
5
Signal A
Signal B
0 [V]
0 / 5 [V]
0 [V]
Pins 8, 9
Set pin 4 to 0 V. Input signal A and measure the distortion
factor (THD M [%]).
Set pin 4 to 5 V. Input signal B and measure the distortion
factor (THD S [%]).
6
Signal A
Signal B
Signal E
0 [V]
0 / 5 [V]
0 [V]
Pins 8, 9
Set pin 4 to 0 V. Input signal B and measure the output level
(SM). Next, measure its output level (NM) on no signal input
condition.
S / N M [dB] = 20 og (SM / NM)
Set pin 4 to 5 V. Input signal B and measure the output level
(SS). Next, input signal E and measure its output level (NS).
S / N M [dB] = 20 og (SS / NS)
7
Signal E
0 [V]
0 / 5 [V]
0 [V]
Pins 8, 9
Set pin 4 to 0 V and set LPF output to through. Measure the
output level (VLeak M).
Set pin 4 to 5 V and set LPF output to through. Measure the
output level (VLeak S).
