Dual High Frequency Differential Ampli鏗乪r
For Low Power Applications Up to
500MHz
The CA3102 consists of two independent differential
ampli鏗乪rs with associated constant current transistors on a
common monolithic substrate. The six transistors which
comprise the ampli鏗乪rs are general purpose devices which
exhibit low 1/f noise and a value of f
T
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 鏗俥xibility.
The monolithic construction of the CA3102 provides close
electrical and thermal matching of the ampli鏗乪rs. 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 鏗俥xibility.
