General Description

The EL4451C is a complete variable gain circuit It offers wide

bandwidth and excellent linearity while including a powerful

output voltage amplifier drawing modest supply current

The EL4451C operates on g5V to g15V supplies and has an

analog input range of g2V making it ideal for video signal

processing AC characteristics do not change appreciably over

the g5V to g15V supply range

The circuit has an operational temperature range of b40 C to

a85 C and is packaged in plastic 14-pin DIP and 14-lead SO

The EL4451C is fabricated with Elantec’s proprietary comple-

mentary bipolar process which provides excellent signal sym-

metry and is free from latch up
