The CA3102 consists of two independent differential
amplifiers with associated constant current transistors on a
common monolithic substrate. The six transistors which
comprise the amplifiers are general purpose devices which
exhibit low 1/f noise and a value of fT in excess of 1GHz.
These features make the CA3102 useful from DC to
500MHz. Bias and load resistors have been omitted to
provide maximum application flexibility.
The monolithic construction of the CA3102 provides close
electrical and thermal matching of the amplifiers. This
feature makes this device particularly useful in dual channel
applications where matched performance of the two
channels is required.
The CA3102 has a separate substrate connection for greater
design flexibility.
