CA3102
FN611.7
Dual High Frequency Differential Amplifier
For Low Power Applications Up to
500MHz
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.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
