CA3102

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

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.
