Signal processing
Power supply ripple rejection
at VP(rms) ≤ 200 mV; f = 100 Hz; Gv = 0 dB
Channel separation (250 Hz to 10 kHz)
at Gv = −20 to + 21.5 dB
Spread of volume control with
constant control voltage V1-18 = 0.5 V17-18
Gain tolerance between left and right
channel V16-18 = V1-18 = 0.5 V17-18
Tracking between channels
for Gv = 21.5 to −26 dB
f = 250 Hz to 6.3 kHz; balance adjusted at
Gv = 10 dB
Signal handling with DC feedback
Input signal handling
at VP = 8.5 V − 15 V; THD = 0.7%;
f = 1 kHz (RMS value)
Output signal handling (note 2 and note 3)
at VP = 8.5 V; THD = 0.7%;
f = 1 kHz (RMS value)
Noise performance (VP = 12 V)
Output noise voltage (unweighted; Fig.14)
at f = 20 Hz to 20 kHz (RMS value; note 4)
for Gv = −16 dB (note 5)
