In 1969, the first triple operational transconductance
amplifier or OTA was introduced. The wide acceptance of
this new circuit concept prompted the development of the
single, highly linear operational transconductance amplifier,
the CA3080. Because of its extremely linear
transconductance characteristics with respect to amplifier
bias current, the CA3080 gained wide acceptance as a gain
control block. The CA3094 improved on the performance of
the CA3080 through the addition of a pair of transistors;
these transistors extended the current carrying capability to
300mA, peak. This new device, the CA3094, is useful in an
extremely broad range of circuits in consumer and industrial
applications; this paper describes only a few of the many
consumer applications.
