The CA3054 consists of two independent differential amplifiers with associated constant current transistors on a common monolithic substrate. The six NPN transistors which comprise the amplifiers are general purpose devices which exhibit low 1/f noise and a value of f_T in excess of 300MHz. These feature make the CA3054 useful from DC to 120MHz. Bias and load resistors have been omitted to provide maximum application flexibility.

The monolithic construction of the CA3054 provides close electrical and thermal matching of the amplifiers. This feature makes these devices particularly useful in dual channel applications where matched performance of the two channels is required.
