The CA3060 monolithic integrated circuit consists of an array of
three independent Operational Transconductance Ampliï¬ers
(see Note). This type of ampliï¬er has the generic characteris-
tics of an operational voltage ampliï¬er with the exception that
the forward gain characteristic is best described by transcon-
ductance rather than voltage gain (open-loop voltage gain is the
product of the transconductance and the load resistance,
gMRL). When operated into a suitable load resistor and with
provisions for feedback, these ampliï¬ers are well suited for a
wide variety of operational-ampliï¬er and related applications. In
addition, the extremely high output impedance makes these
types particularly well suited for service in active ï¬lters.
The three ampliï¬ers in the CA3060 are identical push-pull
Class A types which can be independently biased to achieve a
wide range of characteristics for speciï¬c application. The elec-
trical characteristics of each ampliï¬er are a function of the
ampliï¬er bias current (IABC). This feature offers the system
designer maximum ï¬exibility with regard to output current capa-
bility, power consumption, slew rate, input resistance, input bias
current, and input offset current. The linear variation of the
parameters with respect to bias and the ability to maintain a
constant DC level between input and output of each ampliï¬er
also makes the CA3060 suitable for a variety of nonlinear appli-
cations such as mixers, multipliers, and modulators.
In addition, the CA3060 incorporates a unique Zener diode
regulator system that permits current regulation below sup-
ply voltages normally associated with such systems.
NOTE: Generic applications of the OTA are described in AN-6668.
For improved input operating ranges, refer to CA3080 and CA3280
data sheets (File Nos. 475 and 1174) and application notes AN6668
and AN6818.
