Stereo Amplifier With Gain Control
Figure 24 shows a stereo amplifier with variable gain via
a control input. Excellent tracking of typical 0.3 dB is easy
to achieve. With the potentiometer, R
P
, the offset can be
adjusted. For AC-coupled amplifiers, the potentiometer
may be replaced with two 510 resistors.
Modulators
Because the transconductance of an OTA (Operational
Transconductance Amplifier) is directly proportional to I
ABC
,
the amplification of a signal can be controlled easily. The
output current is the product from transconductance
×
input
voltage. The circuit is effective up to approximately 200 kHz.
Modulation of 99% is easy to achieve.
