The CA3049T and CA3102 consist of two independent
differential amplifiers with associated constant current
transistors on a common monolithic substrate. The six tran-
sistors which comprise the amplifiers are general purpose
devices which exhibit low 1/f noise and a value of fT in
excess of 1GHz. These feature make the CA3049T and
CA3102 useful from DC to 500MHz. Bias and load resistors
have been omitted to provide maximum application flexibility.
The monolithic construction of the CA3049T and CA3102
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.
The CA3102 is like the CA3049T except that it has a
separate substrate connection for greater design flexibility.
Formerly Developmental Type No. TA6228.
