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
