TP12 40 40 72 00 72 40 * 10 (b) l Apply 9.0 V DC and sine wave
TP13
(60 Hz, 500 mV_rms) to V_CC
terminal.
TP16
l Measure amplitude of TP12,
TP13 and TP16 (vTP12 mV_rms,
vTP13 mV_rms, vTP16 mV_rms).
l RR1 W dB = 20 ℓog (vTP12 / 500)
RR1 R dB = 20 ℓog (vTP13 / 500)
RR1 L dB = 20 ℓog (vTP16 / 500)

TP13
to TP6 and TP8.
TP16
l Increase amplitude of the input
signal, and measure THD of
TP13 and TP16.
l Measure amplitude of TP13 and
TP16 when THD of the output is
1% (v_DOUT R1 V_p-p, v_OUT L1
V_p-p).
l Input signal (10 kHz, sine wave)
to TP6 and TP8.
l Increase amplitude of the input
signal, and measure THD of
TP13 and TP16.
l Measure amplitude of TP13 and
TP16 when THD of the output is
1% (v_DOUT R2 V_p-p, v_DOUT L2
V_p-p).
l Smaller value v_DOUT R1 or
v_DOUT R2 is v_DOUT R. Smaller
value v_DOUT L1 or v_DOUT L2 is
v_DOUT L.
l Input signal (80 Hz, sine wave) to
TP6 and TP8.
l Increase amplitude of the input
signal, and measure THD of
TP12.
l Measure amplitude of TP12
when THD of the output is 1%
(v_DOUT W V_p-p).
