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
g
5V to
g
15V and has an analog input
range of
g
0 5V AC characteristics do not change appreciably
over the supply range
The circuit has an operational temperature of

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
