Description

The CA3060 monolithic integrated circuit consists of an array of three independent Operational Transconductance Ampliﬁers (see Note). This type of ampliﬁer has the generic characteris- tics of an operational voltage ampliﬁer 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, g M R L). When operated into a suitable load resistor and with provisions for feedback, these ampliﬁers are well suited for a wide variety of operational-ampliﬁer and related applications. In addition, the extremely high output impedance makes these types particularly well suited for service in active ﬁlters. The three ampliﬁers in the CA3060 are identical push-pull Class A types which can be independently biased to achieve a wide range of characteristics for speciﬁc application. The elec- trical characteristics of each ampliﬁer are a function of the ampliﬁer bias current (I ABC ). This feature offers the system designer maximum ﬂexibility 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 ampliﬁer 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. Pinout CA3060 (PDIP) TOP VIEW +AMP 1 BIAS REG.
