General Description

The EL4452 is a complete variable-gain circuit It offers wide

bandwidth and excellent linearity while including a powerful

output voltage amplifier drawing modest current The higher

gain and lower input noise makes the EL4452 ideal for use in

AGC systems

over the supply range

and is packaged in 14-pin P-DIP and SO-14

The EL4452 is fabricated with Elantec’s proprietary comple-

mentary bipolar process which gives excellent signal symmetry

and is very rugged
