EL4451

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.
