Dual Independent Differential Amp for
Low Power Applications from DC to
120MHz
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.
