General Description
The EL4430 and 4431 are video instrumentation amplifiers
which are ideal for line receivers, differential-to-single-ended
converters, transducer interfacing, and any situation where a
differential signal must be extracted from a background of common-mode noise or DC offset.
These devices have two differential signal inputs and two differential feedback terminals. The FB terminal connects to the amplifier output, or a divided version of it to increase circuit gain,
and the REF terminal is connected to the output ground or
offset reference.
The EL4430 is compensated to be stable at a gain of 1 or more,
and the EL4431 for a gain of 2 or more.
The amplifiers have an operational temperature of
a
85§C and are packaged in plastic 8-pin DIP and SO-8.

The EL4430 and EL4431 are fabricated with Elantec’s proprietary complementary bipolar process which gives excellent signal symmetry and is free from latchup.
