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
g
5V to
g
15V supplies and has an
analog input range of
g
2V making it ideal for video signal
processing AC characteristics do not change appreciably over
the
g
5V to
g
15V supply range
The circuit has an operational temperature range of
b
40 C to
a
85 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
