EL4451
FN7169
Wideband Variable-Gain Amplifier,
Gain of 2
The EL4451 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 EL4451 operates on ±5V to ±15V supplies and has an
analog input range of ±2V, making it ideal for video signal
processing. AC characteristics do not change appreciably
over the ±5V to ±15V supply range.
The circuit has an operational temperature range of -40°C to
+85°C and is packaged in plastic 14-pin DIP and 14-pin SO.
The EL4451 is fabricated with Elantec’s proprietary
complementary bipolar process which provides excellent
signal symmetry and is free from latch up.
