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
The EL4452 operates on g5V to g15V and has an analog input
range of g05V AC characteristics do not change appreciably
over the supply range
The circuit has an operational temperature of b40 Cto a85 C
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
