EL4430C/EL4431C
Video Instrumentation Amplifiers
Features
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 com-
mon-mode noise or DC offset.
# Fully differential inputs and
feedback
Ð Differential input range of
g
2V
g
Ð Common-mode range of 12V
Ð High CMRR at 4 MHz of
70 dB
These devices have two differential signal inputs and two differ-
ential feedback terminals. The FB terminal connects to the am-
plifier 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 EL4430 and EL4431 are fabricated with Elantec’s proprie-
tary complementary bipolar process which gives excellent sig-
nal symmetry and is free from latchup.
