In 1969, the first triple operational transconductanceamplifier or OTA was introduced. The wide acceptance ofthis new circuit concept prompted the development of thesingle, highly linear operational transconductance amplifier,the CA3080. Because of its extremely lineartransconductance characteristics with respect to amplifierbias current, the CA3080 gained wide acceptance as a gaincontrol block. The CA3094 improved on the performance ofthe CA3080 through the addition of a pair of transistors;these transistors extended the current carrying capability to300mA, peak. This new device, the CA3094, is useful in anextremely broad range of circuits in consumer and industrialapplications; this paper describes only a few of the manyconsumer applications.
